A STUDY ON PLASTIC INSTABILITY OF STRUCTURES IN PLANE STRESS UNDER PROPORTIONAL LOADING

摘要：

In this paper, plastic instability of several structures in plane stress under proportional loading is studied. For materials with stress-strain relationship of Swift type, strain at instability can be deduced to be considered as a failure criterion. Meanwhile, the strength of the structure can be calculated according to the stress-strain relationship. Finite element analysis and bursting experiments are performed to six thin shell cylindrical vessels with varies materials and dimensions respectively. The results of calculations and experiments demonstrate that it is accurate and reasonable to adopt instability strain as a failure criterion.
