| 摘 要： | 针对橡胶类材料大应变时硬化现象，采用国家GB528标准，在室温下通过单轴拉伸本构实验，建立了基于主伸长的连续介质力学的新本构模型，并确定应变能密度函数中的本构参数，再利用简单剪切实验进行参数验证，表明新本构关系的可行性与有效性．最后将新本构方程加入通用有限元软件，利用非线性有限元对平面应力橡胶板进行了计算．

| Abstract: | The new constitutive function of rubber-like materials with hardening phenomenon is established in this article, basing on the experiment of simple axial extensibility according to the national related norm GB528. The constitutive data for the new model is fitted and the simple shearing experiment is utilized to prove the feasibility of the constitutive equation produced in this paper. At last a rubber-like materials member with plane-stress is calculated by the new constitutive function inserted in the current FEM software. |
