Static Analysis of Thick Functionally Graded Axisymmetric Conical Shell Under Thermal and Mechanical Load Using Differential Quadrature Method

In this paper thermoelastic behavior of a functionally graded material (FGM) conical shell with clamped edges condition is investigated. Material properties vary according to power law along the thickness direction. Thermo elastic properties of the shell are assumed to vary along the thickness by a power law distribution with Poisson ratio is held to be constant. By using first order shear deformation theory، strain-displacement relations and constitutive equations، governing differential equations can be derived in term of mid radius displacements and rotation. By using the differential quadrature method (DQM) the obtained governing equations can be solved. To validate the accuracy of the present procedure، numerical results were compared with those available in published literature. Finally the effect of gradient index، geometry dimension and thermo mechanical load on the bending behavior of conical shell is considered.
