Statical shakedown analysis with temperature-dependent yield condition

摘要

This paper describes a general statical approach for shakedown analysis of structures of perfectly plastic material using non-linear optimization. The developed methods may be implemented with any displacement-based finite element code. The temperature-dependence of the yield limit is taken into account in shakedown analysis. Temperature-dependent shakedown analysis of a pipe-junction and a thick tube are performed by different methods.
