Fracture toughness analysis of aluminum (Al) foil and its adhesion with low-density polyethylene (lpde) in the packing industry

Abstract Liquid food packages consist of various polymers films, which are bonded together with Aluminum foil (Al-foil) using adhesion or by direct heat. The main aim of this research was to define important material properties such as fracture toughness and some FE-simulation material model parameters such as damage initiation, damage evolution, and the adhesion between […]

A Hybrid Crack Detection Approach for Scanning Electron Microscope Image Using Deep Learning Method

Abstract The scanning electron microscope (SEM) is widely used in the analysis and research of materials, including fracture analysis, microstructure morphology, and nanomaterial analysis. With the rapid development of materials science and computer vision technology, the level of detection technology is constantly improving. In this paper, the deep learning method is used to intelligently identify […]

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 […]

Trouser tear testing of thin anisotropic polymer films and laminates

Abstract This research has investigated the essential work of fracture (EWF) from trouser tear test of polyethylene terephthalate (PET), low-density polyethylene (LDPE) films and their corresponding laminate using a convenient cyclic tear test method. Propagation of tear crack in these thermoplastics deflects from the initial crack path due to the material anisotropy. An improvement to […]

Masters thesis opportunities in testing and finite element simulation of packaging materials

Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Introduction of new packaging materials or package opening techniques for better user experience, forces new design measurements which require a large number of prototype developments and physical testing. In order to achieve more rapid and robust designs, […]
