摘要: 本文导出了厚壁圆筒在初次加载、卸载以及重新加载时的应力强度。利用弹塑性分析方法研究了受内压作用下厚壁圆筒的安定性,得到了关于服从各向同性强化规律和服从随动强化规律的弹性-幂强化厚壁圆筒的安定载荷。

Abstract: This paper is concerned with stress strength of thickwall cylindrical tube under internal pressure during loading, unloading and reloading. By using elastic-power hardening model the shake-down load of such thickwall cylindrical tube are obtained for isotropic and kinematical hardening assumptions.
