Tearing Energy and Crack Growth Rate of a Kind of Natural Rubber

天然橡胶撕裂能和疲劳裂纹扩展速率研究

The variation of tearing energy with crack size was calculated for the bonded crack of simple shear rubber using non-linear finite element analysis.

通过有限元分析方法模拟简单剪切橡胶件粘结处裂纹扩展时撕裂能与裂纹尺寸的关系。

For small cracks the tearing energy was dependent on the crack length, while the tearing energy was constant for long carack.

在小裂纹情况下，撕裂能强烈依赖于裂纹尺寸；

Finite element analysis results for the tearing energy agreed with the previous solution for long cracks.

在裂纹尺寸较大时，撕裂能为常值，与裂纹尺寸无关，有限元解与分析解吻合很好。

Three energy dissipation mechanisms are involved: tearing energy, plastic bending energy and friction energy during the specimens deformation.

对实验结果的分析中认为耗散能主要由撕裂能、塑性弯曲变形能和摩擦能3部分构成。

Calculations of tearing energy are made for a rubber pure shear specimen with a central crack or a edge crack in the specimen or at the rubber-to-steel bond.

对橡胶纯剪试件中或橡胶与钢性夹具粘结处存在中心裂纹和边缘裂纹时的撕裂能进行了计算。
