1. 1. Validation of Finite Element Model of a Tetra Pak Package

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
   Keywords : Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

   Abstract : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

3. 2. Crystal Plasticity Finite Element Modelling of Tin Crystals Using Phase Fields

   University essay from Lunds universitet/Hållfasthetslära

   Author : Viktor Hultgren; [2018]
   Keywords : crystal plasticity; finite deformation; phase field; MOOSE; FEM; Technology and Engineering;

   Abstract : Tin whiskers have long caused issues to electronic components and made the subject of many articles. According to NASA the oldest reports concerning whiskers date back to the 1940's. The whiskers are single-crystals growing from, for example electronic components. READ MORE

4. 3. Additive weld manufacturing and material properties effect on structural margins

   University essay from KTH/Lättkonstruktioner

   Author : Daniel Arvidsson; [2018]
   Keywords : ;

   Abstract : the FE analyses. Traditionally all parts are modeled with isotropic base material. Analyses are made on a part of the nozzle which includes both a butt weld and metal deposition and which is an interface to another part causing loads that has to be sustained by the weld and the MD.

5. 4. Topology Optimization for Additive Manufacturing Considering Stress and Anisotropy

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Henrik Alm Grundström; [2017]
   Keywords : Topology Optimization; Stress Constraints; Additive Manufacturing; Anisotropic Material Proporties;

   Abstract : Additive manufacturing (AM) is a particularly useful manufacturing method for components designed using topology optimization (TO) since it allows for a greater part complexity than any traditional manufacturing method. However, the AM process potentially leads to anisotropic material properties due to the layer-by-layer buildup of parts and the fast and directional cooling. READ MORE

6. 5. Dual-Probe Shear Wave Elastography in a Transversely Isotropic Phantom

   University essay from KTH/Skolan för teknik och hälsa (STH)

   Author : Gioia Bassan; [2015]
   Keywords : Shear Wave Elastography; Transversely isotropic phantom;

   Abstract : Shear Wave Elastography (SWE) is an ultrasound based technique which is able to measure tissue stiffness through the speed of induced shear waves. Tissue stiffness is often related to pathological conditions and detecting mechanical changes can help the recognition of potential diseases. READ MORE
