有限元分析中橡胶应变能函数的若干形式

介绍在有限元分析中描述橡胶力学性能常用的应变能函数。以应变不变量表示的应变能函数，较常用的有Ｒｉｖｌｉｎ 模型、ｎｅｏＨｏｏｋｅａｎ 模型、ＭｏｏｎｅｙＲｉｖｌｉｎ 模型、ＧｅｎｔＴｈｏｍａｓ 模型、ＮｉｃｈｏｌｓｏｎＮｅｌｓｏｎ 模型等；以伸张率表示的应变能函数常用的有ＶａｌａｎｉｓＬａｎｄｅｌ 模型、ＰｅｎｇＬａｎｄｅｌ 模型和Ｔｏｂｉｓｃｈ 模型、Ｏｇｄｅｎ 模型等。这些模型各有其特点和适用性。

Some Forms of Strain Energy Function for Rubber with Finite Element Analysis

The strain energy functions to characterize the mechanical properties of rubber with FEA are described.The common strain energy functions expressed as strain invariables include Rivlin model, neo Hookean model,Mooney Rivlin model,Gent Thomas model and Nicholson Nelson model etc.;the common strain energy functions expressed as elongations include Valanis Landel Model,Peng Landel model,Tobisch model and Ogden model etc..The models have different characteristics and suitable applications.
