1. 1. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : Erik Stålbrand; [2023]
   Keywords : Solid Mechanics; Material Modelling; Damage Modelling; Sheet Metal Damage; Punching Simulation; Forming Simulation; Heat Exchanger; Technology and Engineering;

   Abstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

3. 2. Study of non-linear strain path in sheet metal forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Chandramohan Aisvaran; [2021]
   Keywords : ;

   Abstract : At present, Sheet Metal Forming (SMF) is not just limited to increasing demand from automobile industries but also to various other manufacturing industries that utilize sheet metal forming processes. The surplus demands for optimised manufacturing products warrant the need for an extended decisive study on SMF. READ MORE

4. 3. Material parameter identification of a thermoplastic using full-field calibration

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Nikhil Prabhu; [2020]
   Keywords : DIC; FFC; Thermoplastics; Material parameter identification; multi-point history; Polyamide 6; GISSMO; Response Surface Methodology;

   Abstract : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. READ MORE

5. 4. Virtual testing of self-piercing rivet connections

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Daniel Andersson; Fredrik Saliba; [2020]
   Keywords : FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

   Abstract : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). READ MORE
