A sector in-plane finite element for analysis of multi-layer cylinders exposed to pressure and thermal loading

Abstract

In this paper, analysis of multi-layer cylinders exposed to pressure and thermal loading is considered using a sector element based on the strain approach. Materials in cylinder layers have been assumed to be linearly elastic, homogeneous, and isotropic. The sector in-plane finite element employed is defined in the polar coordinate system with three degrees of freedom at each corner node (the two translations and the in-plane rotation). The results of displacement and stresses obtained in the present paper are compared with the analytical solutions, and a good accuracy shown.
