1. 1. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram

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

   Författare :Elin Olofsson; Mohammed Al-Fadhli; [2022]
   Nyckelord :Forming Limit Diagram; Forming Limit Curve; Non-Linear Strain Paths; Pre-Straining; Sheet Metal Forming.;

   Sammanfattning : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. LÄS MER

3. 2. Comparison of Accuracy in Sheet Metal Forming Simulation Software

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Alexander Torstensson; [2022]
   Nyckelord :Sheet Metal Forming; Triboform; Autoform;

   Sammanfattning : As competition in the car market increases, the techniques for car manufacturing are developed and becomes more advanced to be able to keep up with the pace. The development process of car body components has shifted over the years to involve more simulation driven testing than ever before to save time and money in the early stages of development.

4. 3. Friction and material modelling in Sheet Metal Forming Simulations

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

   Författare :Herman Bentsrud; [2020]
   Nyckelord :Sheet metal forming; Material model; Triboform; Autoform; Plåtmetalformning; Materialmodell; Triboform; Autoform;

   Sammanfattning : In today’s car manufacturing industry, sheet metal forming is a important process that takes preparation, which is time consuming and complex when new processes are made. When new metal grades and alloys are provided to the industry, tests are conducted to determine it’s behaviour and strengths. LÄS MER

5. 4. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

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

   Författare :Esbjörn Zachén; [2019]
   Nyckelord :Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

   Sammanfattning : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

7. 5. Material modeling in Sheet Metal Forming Simulations : Quality comparison between comonly used material models

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

   Författare :Kevin nilsson; [2019]
   Nyckelord :AutoForm; Material model; Biaxial data; Tesnile test; AutoForm; Material modell; Biaxiella data; Dragprov;

   Sammanfattning : In today's automotive industries, many different simulation programs are used to optimize parts before they come into production. This has created a market for complex material models to get the best possible approximation of reality in the simulation environment. LÄS MER
