The stress distribution on the tip of the cracks and the stress intensity factor on them are the main courses in the fracture mechanic. The stress intensity factor of the cracks with the different load exited and the different geometry are listed in the tables of the standard books. In all of them, the cracks are located in the central point of the plates. In the uniform edge loaded case, the crack position is not effect on the stress intensity factor of the crack but in the case that the load is concentrated the stress distribution different from point to another point and therefore the stress intensity factor of the crack, is changed with the crack displacement from the point of the exited load. In this paper, the stress intensity factor changes with the distance of it from the edge of the semi-infinite plate with the edge crack is investigated. A new relation is introduced from the simulation solution with the Abaqus. Then, similar relation from analytical solution from the theory of the linear fracture mechanic was proposed. This relation was determined from the stress distribution calculation in the plate with the pointed load with the analytical solution from the elasticity theory. This two relations were compared with another and finally the more accurate relation was introduced as the relation of the stress intensity factor with the distance from the edge of the plate.

<br />However, problems such as osteoporosis due to high elasticity of metals relative to bones, and local infections and systemic problems caused by releasing metallic ions have motivated research on replacing metallic screws with non metallic ones. In this study, the composite containing poly-l-lactic acid and bioactive glass fibers were considered for the design of the screw using ABAQUS software (V6.11). The elastic constants were first estimated in micro analysis then transferred to macro analysis for modeling in two-layer situations composed of unidirectional fibers and random fibers (UD/R) and also for modeling in three-layer situations composed of unidirectional fibers, fibers with an angle of ±20 degree in relation to force vector, and random fibers (UD /±20/R) with various percentages of layer thickness. Results show that in the analysis with %65 layers of unidirectional fibers, %10 layers by fibers with an angle of ±20 degree, and %25 of layers with random fibers, flexural modulus, flexural strength, and longitudinal elasticity coefficient were estimated about 22.7 GPa, 347 MPa, and 24.8 GPa respectively, the last one being slightly higher than that of cortical bone. Considering similar results for cortical bones, our designed composite screws are robust enough to replace metal screws for repairing orthopedic fractures

In this paper, the nonlinear vibration analysis of a thin cylindrical shell made of Functionally Graded Material (FGM) resting on a nonlinear viscoelastic foundation under compressive axial and lateral loads is studied. Nonlinear governing coupled partial differential equations of motions (PDEs) for cylindrical shell are derived using improved Donnell shell theory. The equations of motions (EOMs) then are solved using the Galerkin method, Volmir’s assumption and the forth-order Runge-Kutta method to obtain dynamic response of the shell including nonlinear frequencies, frequency-amplitude curves and nonlinear radial deflection for the shell of revolution. Afterward, the effect of changing the value of different parameters on the nonlinear dynamic response of the FGM cylindrical shell considering compressive axial and lateral loads, geometric characteristics of the shell, FGM material distribution along direction of the thickness of the shell and coefficients of the viscoelastic foundation are all investigated

Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in process industries such as oil, gas, petrochemical and power plants, that their health monitoring is vital. The aim of this research is to introduce a technique to illuminate the damages in these equipments by using guided waves. Thereby, two different specimens were used as pressurized vessels at different conditions: pristine and corroded. Different internal pressures were also studied. Piezoelectric transducers were electromechanically coupled to the vessels and the guided waves were propagated by using pitch-catch method. The outcomes indicated that damage parameters in vessels such as corrosion and pressure changes have considerable effect on the signals that piezoelectric sensors receive. Corrosion, the most common damage in pressurized vessels, reduce the signal domain in frequency field to 11%. Also increasing pressure reduce the signal domain.<br />We can used these outcomes to innovate a technique for structural health monitoring of pressure equipmentss.

Loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. One of the most important durability problems in diesel engines is due to the cracks valves bridge area. The purpose of this study is a thermo-mechanical analysis of cylinder heads of diesel engines using a two-layer viscoplasticity model. The results of the thermo-mechanical analysis indicate that the maximum temperature and stress exist in the valves bridge. The results of the finite element analysis correspond with the experimental tests, carried out in references, and illustrate the cylinder heads cracked in this region. The results of the thermo-mechanical analysis show that when the engine is running the stress in the region is compressive caused by the thermal loading and combustion pressure. When the engine shuts off the compressive stress turns into the tensile stress because of assembly loads. The valves bridge is under the cyclic tensile and compressive stress and then is under low-cycle fatigue. After several cycles the fatigue cracks will appear in this region. The lifetime of this part can be determined through finite element analysis instead of experimental tests. Viscous strain is more than the plastic strain which is not negligible

In this paper, a discontinuity in beams whose intensity is adjusted by the spring stiffness factor is modeled using a torsional spring. Adapting two analyses in strong and weak forms for discontinuous beams, the improved governing differential equations and the modified stiffness matrix are derived respectively. In the strong form, two different solution methods have been presented to make an analogy between the formulation of the Euler-Bernoulli and Timoshenko theories that indicates the influence of the shear deformation in discontinuous beams. The flexural stiffness of discontinuous beams is corrected by using the Dirac’s delta function. In the weak form, the reduced stiffness matrix is derived from the strain energy equation established by the continuity, kinematics and constitutive equations. The linearity assumption of the geometry and material is considered to construct the kinematics and constitutive equations respectively. The continuity conditions mathematically connect two divided parts of the Euler-Bernoulli beam for which an improved Hermitian shape function is employed to interpolate displacement field. An application shows the comparison and validation of the results of the strong and weak forms, and also the quasi-static behavior of discontinuous beams.

Mixed convection of Cu-Water nanofluid is studied numerically in a shallow inclined enclosure by applying lattice Boltzmann method. The D2Q9 lattice and internal energy distribution function based on the BGK collision operator are used in order to develop the thermal flow field. The enclosure's hot lid has the constant velocity of U0 while its cold lower wall has no motion. Moreover, sidewalls are taken in to account as adiabatic ones. At 3 modes of convection heat transfer (free convection, force convection and mixed convection), the effects of volume fraction and inclination angle of enclosure are studied for different values of Reynolds number as equal to 10 and 100. Comparison of achieved results as like the streamlines, isotherms and profiles of velocity and temperature versus pervious available ones, implies the appropriate agreement. It is seen that more amount of volume fraction and enclosure inclination angle at the state of free convection would correspond to higher Nusselt number. The incomes of present work show the suitable performance of lattice Boltzmann method in order to simulate the nanofluid mixed convection in an inclined enclosure.

In this research, effect of nanoparticles dimeter on free convection of aluminum oxide-water was investigated in a cavity by single phase and two phase models. The range of Rayleigh number is considered 105-107 in volume fractions of 0.01 to 0.03 for nanoparticles with various diameters (25, 33, 50 and 100 nm). Given that the two phase nature of nanofluids, necessity of modeling by this method is increasing. Single phase approach (in contrary of two phase) for nanofluids is based on that the behaviors of each two solid phase (nanoparticles) and liquid phase (base fluid) are completely similar. In this study, Eulerian-Eulerian approach and mixture model was used given that Brownian motion and thermophoresis effects. Brownian motion and thermophoresis creates under influences of volume fraction gradient and temperature gradient, respectively that cause to creating slip between nanoparticles and base fluid; thus, kind of non-uniformity creates on behavior between nanoparticles and base fluid. This non-uniformity leads to significant effects on results of two phase modeling that creates better agreement to single phase modeling with experimental results. Results indicate that heat transfer decreases with increasing diameter and volume fraction of nanoparticles. Also, effect of nanoparticle diameter on flow and heat transfer is tangible.

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investigated. Cutting tools used in this experiment was a tungsten carbide material, model 890, geometry square shaped and specification of SNMG 120412. Also the tools has been coated using physical vapor deposition by chemical composition of TiN/TiCN/AlTiSiN in both micro and nano layer conditions. According to the results, as the feed rate is increased cutting forces mostly increases in both micro and nano layer coating conditions. . Generally in this research, application of micro layer coating results in less cutting forces compared to nano layer coating, so it can be said that micro layer coating has a better performance
