Determination of material parameters of rubber and composites for computational modeling based on experiment data

Abstract

The article deals with determination of material parameters of elastomer (rubber) for computational modeling based on experiment data - hardness and also determination of materials parameters of specific composite materials for next-generation tires. Mooney-Rivlin parameters of elastomers can be determined on the basis of the Shore A hardness. There are exist equations which can be used conversion of the mentioned hardness to material parameters of elastomers. The procedure is such that the Shore A hardness is converted to the elastic or shear modulus and then Mooney-Rivlin material parameters are determined from the modulus. But these equations can lead to different results for the same hardness. In this paper, these results are comparison. The results can be used as input material data of rubber seals of pump and compressor machinery for their computational modeling. Methods of determination of the modulus of elasticity of composite with elastomer matrix are necessary created based on experimental data of static tensile test of specimens of a radial tire casing. Next results can be applied for simulations of tires with interaction roads which used for modern passenger cars and trucks and the results can be applied for simulation of conveyor belts where elastomer is used.
