Thermo-Elastic-Plastic Stresses in Multi-Layered Cylinders

摘要

One of the many efforts undertaken to increase the life of gun tubes and/or increase their resistance to erosion involves the use of linears fabricated from different materials. A finite difference computer code for investigating the thermo-elastic-plastic response of gun tubes has been expanded to include multi-layered cylinder response to time dependent boundary conditions. Considered are both cyclic heat input and cyclic stress input. Response curves from inputs representative of repeated firing cycles are presented. The emphasis in this report is on the transient temperature response and on the thermo-elastic stresses and mechanical stresses in the layers. (Author)
