Abstract:

 In this paper,first,an equi-biaxial tensile test apparatus for hyperelastic membrane was developed,and the principle and method of the equiaxial tension test were illustrated.Then,the test conditions and the data processing are both investigated.Finally,three kinds of equiaxial tension methods,i.e.,the ideal tension test,the free-corner tension test and the fixed-corner tension test,were simulated with FEA software ABAQUS.It is found that the error of the fixed-corner tension test in a large tension range is small enough to satisfy the requirements of experiments.

Key words:  equiaxial tension, hyperelastic rubber, ABAQUS, constitutive model
