plate shell element

A 16 node shell element with relative degrees of freedom was developed for large deformation analysis of plate and shell structures.

为了简便有效地解决板壳结构的大变形问题，针对16节点相对自由度壳单元进行研究。

The similarity between equivalent stress distribution around the holes in cylindrical shell and its plate model is shown through finite element analysis.

有限元分析表明，开孔圆柱壳与其相应的平板模型在开孔附近的等效应力分布非常相似。

According to Finite Element Method, the impactor is considered as a discrete mass system in terms of 3D solid element with initial velocity, and 2D shell element is used for target plate.

首先采用有限元法，将撞击体离散成由三维实体单元构成的具有一定初始速度的离散质量系统，对靶板采用二维壳单元离散。
