Abstract
In this paper a study on the vibration of thin cylindrical shells with ring supports and made of functionally graded materials (FGMs) composed of stainless steel and nickel is presented. The properties are graded in the thickness direction according to a volume fraction power-law distribution.The cylindrical shells with ring supports which are arbitrarily placed along the shell and impose zero lateral deflections. The study is carried out based on third order shear deformation shell theory (T.S.D.T). The analysis is carried out using Hamilton’s principle. The governing equations of motion of FGM cylindrical shells are derived based on shear deformation theory. Results are presented on the frequency characteristics, influence of ring support position and the influence of clamed-clamped boundary conditions.

Abstract [Persian]
در این مقاله به بررسی ارتعاشات آزاد یک پوسته استوانه‌ای ساخته شده از مواد FGM (تابعی) با رینگ تقویت شده که ترکیبی از فولاد ضد زنگ و نیکل می باشد پرداخته می‌شود. خصوصیات مواد در جهت ضخامت پوسته مطابق قانون توزیع کسر حجمی تغییر می‌کنند. در این مطالعه پوسته‌های استوانه‌ای رینگ تقویت شده دارند و این رینگها به‌طور اختیاری در طول قرار دارند. این مطالعه بر اساس تئوری مرتبه سوم تغییر شکل برشی پوسته انجام شده است و استخراج معادلات حرکت این پوسته استوانه‌ای FGM بر اساس اصل همیلتون انجام شده است. نتایج ارائه شده در این تحقیق شامل فرکانسهای طبیعی، اثر رفتار کسر حجمی، اثر موقعیت رینگ تقویت شده روی پوسته و اثر شرایط مرزی گیردار-گیردار روی فرکانسهای طبیعی پوسته استوانه‌ای FGM است
