[ 1 ] - Magneto-electro-mechanical size-dependent vibration analysis of three-layered nanobeam with initial curvature considering thickness stretching
Thickness stretching effect based on shear and normal deformation theory is used in this paper for magneto-electro-elastic vibration analysis of a three-layered curved nanobeam including a nano core and two piezo-magnetic layers. Size-dependency is included in derivation of governing equations of motion based Eringen's nonlocal elasticity theory. The initial curvature is accounted in calculatio...

[ 3 ] - The Effect of Temperature Dependency on the Thermo-Electro-Elastic Analysis of Functionally Graded Piezoelectric Spherical Shell
Results of electro-thermo-elastic analysis of a functionally graded thick-walled spherical shell made of temperature dependent materials are presented in this article. All material properties are assumed temperature-dependent and also are graded along the thickness direction based on power function. Temperature dependency is accounted for all material properties including, thermal, mechanical a...
[ 4 ] - Thermoelastic Analysis of a Functionally Graded Simple Blade Using First-Order Shear Deformation Theory
In this article, the thermo-elastic behavior of a functionally graded simple blade subjected to the mechanical and thermal loadings is presented, applying a semi-analytical method and a variable thickness cantilever beam model. A specific temperature gradient is employed between the root and the edges of the beam. It is assumed that the mechanical and thermal properties are longitudinal directi...
[ 5 ] - تحلیل تیر تابعی هدفمند با ضخامت متغیر تحت بارهای مکانیکی و حرارتی به‌کمک تئوری تغییر شکل برشی مرتبه اول
در این مطالعه تحلیل ترموالاستیک تیرهای با ضخامت متغیر ساخته‌شده از مواد هدفمند تابعی انجام شده است. هندسه و شرایط مرزی تیر مشابه پره توربین است. تیر تحت ترکیبی از نیروهای عرضی گسترده و نیروهای حجمی حاصل از چرخش آن حول محور عمود بر طول تیر و میدان مشخصی از درجه حرارت قرار دارد. در ریشه تیر، شرایط مرزی گیردار و در لبه آن، به‌صورت آزاد می‌باشد. خواص مکانیکی و حرارتی در راستای طولی تیر به‌صورت توان...
