PROGRAM FOR OUTPUTTING STRESS-STRAIN CURVE EQUATIONS AND DEVICE FOR THE SAME, EVALUATION METHOD FOR PHYSICAL PROPERTIES OF ELASTIC MATERIALS, AND DESIGN METHOD FOR ELASTIC MATERIALS

摘要

Provided is a model capable of evaluating the physical properties of elastic materials in terms of both viscoelasticity and superelasticity. The physical properties of an elastic material are evaluated using a correlation equation for stress and strain that is found based on a Maxwell model, in which an elastic element and a viscous element are disposed in series, and that includes a strain energy density function in which a higher order term for strain invariance is introduced as term pertaining to elasticity.
