Investigation on Contact-impact Algorithm in Dynamic Response Analyses

阐述了工程结构动力响应分析中接触—碰撞界面的处理算法的研究进展 ,并对对称罚函数法 ( Penalty method)进行了详细的讨论。以 LS- DYNA3D中典型的接触界面算例给出对称罚函数法类型接触界面在程序中的具体实现。

Treating the contact-impact surface in analyzing dynamic response of structures is a key in the computer simulation. This paper presents the development of investigation on this algorithm , and the penalty method is discussed in detail. Using the example in LS-DYNA3D code, it is shown how this algorithm is performed. To find an advanced search method is a key to get a new type contact-impact algorithm.
