Product: Abaqus/Explicit
Benefits: Viscoelastic behavior can be modeled with orthotropic/anisotropic elasticity in Abaqus/Explicit.
Description: In Abaqus/Explicit, time domain viscoelasticity can now be used in conjunction with orthotropic/anisotropic elasticity to model rate-dependent material behavior (“Time domain viscoelasticity,” Section 19.7.1). However, the viscoelasticity is assumed to be isotropic: the relaxation function is independent of the loading direction. The anisotropic elastic response of the rate-dependent material can be specified by defining either the instantaneous response or the long-term response of the material.
Viscoelastic behavior can also be modeled when the Hashin damage criteria is used to model damage in fiber-reinforced composites.
