Abstract:

 In this paper,first,the uniaxial cyclic tensile tests of coated fabric Ferrari1302 were conducted,and a series of biaxial tensile tests with different load ratios were carried out on a self- developed multi- function biaxial tensile tester,with detailed uniaxial and biaxial cyclic tension results being obtained.Then,the stress- strain relationship and elastic moduli of the membrane material at different cycle numbers were discussed according to the test results.Moreover,the theoretical formulas of biaxial coupling elastic modulus were deducted,and the influence of stress ratio on the coupling elastic modulus was discussed.The presented work and procedure provide references for the practical design,analysis and pattern cutting of membrane structures.

Key words:  membrane material, biaxial test, mechanical properties, stress- strain relationship, elastic moduli, cyclic loads
