hyperelasticity

The constraint condition for the strain energy density function of incompressible hyperelasticity is proposed.

通过对各种有限元方法的分析比较，适当修改了已有的应变能密度函数的形式使之更适合数值计算。

The evaluation also shows that the modified 8-chains model can characterize accurately the hyperelasticity of tire rubber at different temperatures.

果还表，修正八可以较准确表征不同温度下轮胎胶料的超弹性力学行为。
