Abstract

In this work, a packaging laminate consisting of LDPE (Low Density Polyethylene), Al-foil (Aluminum foil) is focused, and failure due to necking in substrates and interfacial delamination under loading are considered. A coupled elasto-plasticity damage and fracture constitutive model is combined. The proposed constitutive model is incorporated into the FEM code ABAQUS and utilized to simulate a uniaxial tension in the laminate with an interfacial pre-crack. The simulation results show deformation of the laminate agrees well with theoretical results. The new combined constitutive model is proper to study the failure due to necking and interfacial delamination in the laminate. And the interfacial delamination mode in pre-crack tip could be influenced by fracture toughness ratio of mode I, II.
