Abstract
This chapter reports the thermo-mechanical coupled constitutive relationship materials under impact loading. The stiffness matrix is calculated using the bridge model. Elastic-plastic behavior of fiber tows is defined using Hooke’s law and Hill’s anisotropic plasticity model. The elastic-plastic behavior of the matrix is defined using Hooke’s law, J2 isotropic hardening plasticity theory, and von Mises yield criterion. Constitutive equation is constructed with a combination of stiffness damage evolution law, adhesive-cohesive model of interface damage, and thermo-mechanical coupling. The ductile failure and shear failure criteria are introduced to calculate the impact damage.
