对于高度不可压缩的材料，在平面应变有限元分析中使用三角形单元限制了自由度数。编制了采用四边形单元的计算程序，并采用了各种缩短计算时间的方法。提出了一种应变能函数，它可以在远远超出线性经典弹性理论的应变情况下得到解。
Abstract For a highly incompressible material the use of triangular elements in plane-strain finite-element analyses restricts the number of degrees of freedom. A computer programme is developed which uses quadrilateral elements, and various methods of reducing computation time are employed. A strain-energy function is proposed which will enable solutions to be obtained at strains well beyond those of linear classical elasticity theory.
