摘要
从Gurtin型积分方程着手,推导出一种具有很高精度且为无条件稳定收敛的求解动力响应问题的递推计算格式.文中还详细分析了当前截断误差的影响因素并证明了计算结果的收敛程度.
A high precision unconditionally stable algorithm for the computation of linear dynamic structural systems is derived from the Gurtin type integrated equations.Local truncation error analysis is made and the rate of convergence is proved.
