摘　　要：本文利用已知弹性解分析阶跃载荷作用下大挠度回板的弹塑性动力响应，提出了本征函数法。这是对文献［３，４］的进一步发展。此外在文献［３，４］中，解决大挠度问题时，采用基于卡门方程的混合法，但在本文中，采用了位移法，它在进行分析计算时更为有利。In this paper, the elastic-plastic dynamic response of a circular plate with large deflection is analyzed by using known elastic solution. The eigenfunction method is presented for solving our problem. It is a further development for the references [3,4]. In addition, in the referen ces [3,4], the mixed method based on barman's equation is employed for the analysis of large deflection problem, but in this paper, we employ the displacement method which has the advantage for the analysis.
