  1. 1. A Methodology for Evaluating the Performance of Material Models Under Biaxial Loads

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

    Author : Emmie Salomonsson; Ina Ögren; [2023]
    Keywords : Material Model; Biaxial Test; Punch Test; Material Test; POM; Simulation; FEA.; Technology and Engineering;

    Abstract : The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. READ MORE

  3. 2. Non-Linear strain paths in Sheet Metal Forming

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anton Eriksson; [2021]
    Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

  4. 3. IoT smart athletics : Boxing glove sensors implementing machine learning for an integrated training solution

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Konstantinos Sosopoulos; Michael Tareke Woldu; [2021]
    Keywords : IoT; sensors; accelerometer; machine learning; gyroscope; Android; Bluetooth Low Energy;

    Abstract : It is very common in everyday life for people to use data generated by sensors like accelerometers and gyroscopes, whether they are on the mobile phone, smartwatch or other smart devices, for analysis of their movement or tracking their habits. This study is focused on boxing, and proposes a test where the generated data are put through machine learning algorithms in order to output information on the type of punch thrown by the user.

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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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. READ MORE
