摘要

A global secant relaxation(GSR) method which has been proved to be reliable and effective in accelerating the iterative computation of nonlinear finite element problems is used to improve the convergency performance of the constant elastic stiffness iteration in carrying out the elastic-plastic finite element analysis of cracked structures subjected to cyclic load. The constant elastic stiffness iteration by using large load increment to cyclically change the loading history from one extreme value to the other one is suitable for solving the specified engineering problems since only response information at the extreme loading states is needed to be known. Highly local and global convergences can efficiently be assured by using the GSR improvement though the phenomenons of global unloading and locally reverse plastic flow do exist in the analysis process. The numerical results obtained can be used to assess the elastic-plastic fatigue damage of the structure models been solved.
