   Sammanfattning : The car industry produces many of their car parts by using sheet metal forming, where one of the most time-consuming phases is the development and manufacturing of new forming tools. As of today, when a new tool is to be evaluated in terms of usability, a forming simulation is conducted to predict possible failures before manufacturing. LÄS MER

3. 2. Industrial Sheet Metal Forming Simulation with Elastic Dies

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Markus Lind; Viktor Sjöblom; [2018]
   Nyckelord :Elastic Stamping Dies; FEA; LS-Dyna; Sheet Metal Forming; Structural Analysis;

   Sammanfattning : As part of the development process for new stamping dies, in the automotive sheet metal forming (SMF) industry, the majority of all forming operations are simulated with the Finite Element Method (FEM) before the dies are manufactured. Today, these simulations are conducted with rigid tools under the assumption that there are no tool deformations.

4. 3. Investigation of Friction Modelling and Elastic Tooling influences on the Springback Behaviour in Sheet Metal Forming Analysis

   Master-uppsats, Institutionen för ingenjörsvetenskap

   Författare :Wei Chen; [2011]
   Nyckelord :Springback; friction model; elastic tools; sheet metal forming;

   Sammanfattning : Sheet metal forming is one of the most common forming processes used in the industry, especially in the automotive industry. It becomes a common sense, that by increasing the accurate simulation of sheet metal forming, the industry can save dramatic cost in trial-and-error process when designing the sheet metal forming tools.

5. 4. Investigation and implementation of nonlinear micro plasicity in abaqus

   Master-uppsats, KTH/Industriell produktion

   Författare :Mohammad Tavakol; [2011]
   Nyckelord :;

   Sammanfattning : This thesis is aimed to investigate different approaches in FEM simulation of sheet metal forming to accurately predict the final geometry. These approaches are mainly focused on the behavior of material models used in the forming process. Two sets of test results are available that play important roles in this project. LÄS MER
