Direct Integration Methods With Integral
Model for Dynamic Systems
摘要
Abstract
A new approach which is a direct integration method with integral model (DIM_IM) to solve dynamic governing equations is presented. The governing equations are integrated into the integral equations. An algorithm with explicit and predict_correct and self_starting and four order accuracy to integrate the integral equations is given. Theoretical analysis and numerical examples show that DIM_IM discribed in this paper suitable for strong non_linear and non_conservative system have higher accuracy than central difference，Houbolt，Newmark and Wilson_Theta methods.关键词
