BEHAVIOR OF A BI-MATERIAL CYLINDER INCLUDING THE EFFECTS OF FRACTURE

摘要

A finite element method is presented which utilizes a three dimensional quadrilateral finite element with a stiffness matrix developed in cylindrical coordinates. The method is used to study the behavior of layered cylinders due to asymmetric static thermal loadings. Two types of bonding, rigid and flexible are considered. Additional examples including a pressurized thick walled cylinder and a cylindrical shell under pressure and thermal loadings are presented.
