1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Arthur Barakat; [2023]
   Keywords : Technology and Engineering;

   Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

3. 2. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

   University essay from KTH/Materialvetenskap

   Author : Atharva Kotasthane; [2023]
   Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

   Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE

4. 3. 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.

5. 4. Comparison of Accuracy in Sheet Metal Forming Simulation Software

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Alexander Torstensson; [2022]
   Keywords : Sheet Metal Forming; Triboform; Autoform;

   Abstract : 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.

6. 5. Simulation of GPHE diagonal based on full material history

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

   Author : Anna Gunnarsson; Jenny Hoang; [2021]
   Keywords : Technology and Engineering;

   Abstract : The objectives for this thesis is to further develop a finite element analysis methodology where the material history is evaluated in every step. The processing of the plate from coil to fully formed plate mounted in a heat exchanger should be taken into consideration. Material phenomena such as necking and springback are important to capture.
