A mixed semi-analytical cum numerical approach is presented in this paper which accounts for the coupled mechanical and electrical response of piezoelectric, functionally graded (FG) and layered composite hollow circular cylinders of finite length. Under axisymmetric mechanical and electrical loadings, the three-dimensional problem (3D) gets reduced to a two-dimensional (2D) plane strain proble...

In this paper, finite element elastic contact analysis of a functionally graded (FG) hollow brake disk in contact with pad, subjected to rotation, contact pressure and frictional heat is presented. The material properties vary through the thickness according to a power-law characterised by a grading index, n. The material property is purely steel at the core part and gradually moves and appr...

In this article, a novel spectral method based on the integral transform and finite element is introduced for nonlinear thermal analysis of hollow cylinder under asymmetric boundary excitations. The material properties are temperature-dependent vary in terms spatial coordinates. This dependency makes problem to be nonlinear. intended heat conduction equation discretized using FEM radial directi...

Introduction. Functionally graded materials are of great use, because heterogeneity properties enables to control the strength and rigidity structures. This has caused interest in topic world scientific literature. The construction solutions such problems depends significantly on type boundary conditions. In this paper, we consider equilibrium a thin-walled circular cylinder whose mechanical ch...

Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...

Using the Frobenius series method (FSM), an analytical solution is developed to obtain mechanical stresses of thick spherical pressure vessels made of functionally graded materials (FGMs). The cylinder pressure vessel is subjected to uniform internal pressure. The modulus of elasticity is graded along the radial direction according to power functions of the radial direction. It is assumed that ...
