平面四节点有限元程序，希望学习的同学有个好的起点哟。-Planar four-node finite element program, the students want to learn there is a good starting point yo.

结构有限元四边形四节点分析程序 船舶结构力学编程-Structural finite element quadrilateral four-node analysis program

计算二维薄板应力与应变，采用平面四节点板单元，精度较高。(The stress and strain of two dimensional thin plate are calculated. The plane four node plate element is used to calculate the stress and strain of the plate.)
