摘要
考虑壳体厚向应力应变的壳单元是当前国际上的研究热点,在阐述该壳单元的概念、理论背景及研究方法的基础上,提出了构造该类型单元模型的几个关键问题及技术实现方法,并对该理论模型的应用前景作了展望.
A new kind of shell element with through-thickness stretch has been the international hot research topic. Based on the concept, related theoretical background and research methods of the shell element, several key problems and technical implementation for constructing the element model were proposed. At last the development trend and application prospect of the shell element model are predicted.
