ON HYPERELASTIC CONDITION OF RATE-FORM ELASTICPLASTIC CONSTITUTIVE LAW AT FINITE DEFORMATION

  • It is proved that if the objective stress rate is taken as the Oldroyd rate of the Kirchhoff stress tensor, the integrability condition of the rate-form elastic constitutive law is λ=0, provided that the Lame parameters λ and μ are. constants. This fact renders the rate-form elastic-plastic constitutive law incompatible with the hyperelastic framework in the regime of finite deformation. Several particular situations in which the rate-form elastic con-stitutive laws can be approximately applied to the case ...
