Thermal Buckling Analysis of Circular FGM Plate with Actuator/Actuator Piezoelectric Layer Based on Neutral Plane
In this paper, the thermal buckling analysis of a circular plate made of FGM materials with actuator/actuator piezoelectric layers based on neutral plane, classical plate theory and first order shear deformation plate theory is investigated. Reddy's model is assumed for material properties of FGM plate. Plate under the thermal loading, nonlinear temperature rise through the thickness and clamped edges is considered. Equilibrium and stability equations are drived using the calculus of variations and applying Euler equations. The obtained results are compared with the numerical values of the critical buckling temperature based on the theories mentioned above, and good agreement is observed between them.

Abstract [Persian]
در این مقاله، کمانش حرارتی ورق دایره‌ای شکل ساخته شده از مواد مدرج تابعی با لایه‌های محرک- محرک پیزوالکتریک براساس محل صفحه خنثی و به کمک تئوری کلاسیک صفحات و تئوری مرتبه اول تغییر شکل برشی صفحات بررسی شده است. خواص ورق مدرج تابعی براساس مدل ردی در نظر گرفته شده است. ورق تحت بارگذاری حرارتی، افزایش غیر خطی درجه حرارت در راستای ضخامت و با شرایط مرزی گیردار فرض شده است. معادلات تعادل و پایداری با استفاده از حساب تغییرات و اعمال معادلات اویلر به دست آمده است. در پایان، مقادیر اختلاف دمای بحرانی کمانش براساس تئوری‌‌های یاد شده برای یک ورق نمونه با نتایج به دست آمده توسط سایر محققان مقایسه شده است که تطابق خوبی بین آنها مشاهده شد
