AN EXPLICIT FINITE DIFFERENCE METHOD FOR VISCOELASTIC DYNAMIC PROBLEM

Li Xiaojun Liao Zhenpeng Du Xiuli(Institute of Engineering Mechanics,SSB)  
Based on the basic assumptions of centre difference method and Newmark's method,an explicit difference method for viscoelastic dynamic equation is presented in this paper. Its stability is similar to that of centr,e difference method and its accuracy is not lower than O(△t2).
