Abstract:
1. A method of computing an energy loss generated in a viscoelastic material, comprising the steps of: analyzing a dynamic behavior of an object composed of a viscoelastic material by a numerical analysis method; and computing said energy loss of said object momently when said object makes said dynamic behavior by a viscous component of said object, wherein the viscoelastic material is a thermoplastic resin, a thermosetting resin, an elastomer, or a rubber composition, wherein said numerical analysis method is carried out by an analysis using a finite element method; and said energy loss is computed by using a value of a stress generated by viscosity of said viscoelastic material, when said object makes said dynamic behavior, and wherein said value of said stress generated by said viscosity is found by a viscous drag of a viscous component of said viscoelastic material and by a strain speed of said viscoelastic material at a time when said viscoelastic material makes said dynamic behavior.
