1	Crack propagation in 3D-printed PLA Stenborg, Johan, Ramirez Flores, Amaro January 2022 (has links) Cracks form in all materials. This project was about investigating the crackpropagation in 3D-printed PLA. Both simulations and experiments has beenperformed to get the results. The simulations used a already written code to solvethe problem with FEM. It turned out to be much harder then anticipated to getthe simulations to run as they should. Both simulations and experiments wheresupposed to be executed with 3 point bending, but because of convergence problemsin the simulations, simplifications where made. When comparing the simulationsand experiments, no trustworthy conclusions could be made. There are a lot ofsources of error in this project. But with a bit more time and experience with theused software, it should be able to get some good results which one could use tosimulate other material cracking.
