PREDICT | 2020-

The purpose of PREDICT is to achieve increased accuracy in failure predictions by developing advanced material models, calibration techniques and effective finite element simulations, which can enable unambiguous and reliable formability predictions. Specially, simulation failure predictions of phenomena such as non-linear strain paths, effect of strain rate, anisotropy and presence of edge cracks will be […]

Modeling and Study of Fracture and Delamination in a Packaging Laminate

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 […]
