Abstract
In this work is presented the formulation for static bending of functionally graded axisymmetric plate/shell type structures subjected to axisymmetric mechanical loading under thermal environment. The formulations accounts for linear, geometric and material nonlinear behaviours. A finite element model is implemented and is based on a simple conical frustum finite element with 2 nodes, and 3 degrees of freedom per node, and it shows to be extremely efficient in the analysis of axisymmetric shells subjected to axisymmetric loading. The solution of an illustrative pressure vessel example is presented and discussed.
