Experimental and numerical assessment of the work of fracture in injection-moulded low-density polyethylene

ABSTRACT The fracture mechanics properties of injection-moulded low-density polyethylene (LDPE) sheets were investigated both experimentally and numerically. The total work of fracture was determined experimentally, by means of fracture mechanics testing of sheets of injection-moulded LDPE with side cracks of different lengths. A multi-specimen method, proposed by Kim and Joe (1987), was employed. The total […]

Powerful Modelling Techniques in ABAQUS to Simulate Failure of Laminated composites

ABSTRACT In this study, laminated composites consisting of LDPE (Low Density Polyethylene), Al-foil (Aluminum foil)and an adhesive interface layer is focused. The defects like necking in LDPE, Al-foil layer and interfacial delamination can significantly impact the loading capacity of the laminated material. However, the influence mechanisms of the defects are still unclear, and no appropriate […]

Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

Licentiate thesis of Eskil Andreasson, presented at BTH 2015-05-08.. Abstract A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. To […]
