Abstract The investigation focusing on the mechanical behaviors at the microstructural
level in composite materials can provide valuable insight into the failure
mechanisms at larger scales. A micromechanics damage model which comprises
the coupling of the matrix constitutive model and the cohesive zone (CZM) model
at fiber-matrix interfaces is presented to evaluate the transverse tensile damage
behaviors of unidirectional (UD) fiber-reinforced polymer (FRP) composites.
For the polymeric matrix that exhibits highly non-linear mechanical responses,
special focus is paid on the formulation of the constitutive model, which characterizes
a mixture of elasticity, plasticity as well as damage. The proposed constitutive
model includes… More >
