材料非线性结构的动态子结构法

Dynamic Substructure Method for Material Nonlinear Structure Analysis

将ＢＨ模态综合法推广到材料非线性体系中，采用子结构凝聚法求解非线性动力体系的振动响应，方法简捷，求解体积小，是分析非线性动力问题的一种有效方法．算例表明，该方法运行时间比常规有限元法短。

The B H Modal synthesis method is applied to the non linear dynamic system.The substructure in the cohesive method is used to solve the vibration response of the non linear dynamic system in the analysis of the non linear dynamic system.The method has such advantages as simplicity,accurate physical concept,and small computation volume.
