Abstract:
1. A simulation method for estimating performance of a product made of a viscoelastic material, comprising the steps of: measuring at a moment a value of a strain, a strain speed, and a stress generated in said viscoelastic material in a measuring condition equivalent to a state in which said product is actually used; computing a plurality of different moduli of direct elasticity from history data of said strain and that of said stress and deriving a relationship among said strain, said strain speed, and said modulus of direct elasticity; setting said product made of said viscoelastic material as a product model of which performance is analyzed and inputting said relationship among said strain, said strain speed, and said modulus of direct elasticity to said product model; and simulating in consideration of a phenomenon that said modulus of direct elasticity changes depending on a variation of said strain and said strain speed, whereby the performance of the viscoelastic model made of said viscoelastic material is estimated.
