1. 16. Crack growth based FEM with embedded discontinuities

   University essay from KTH/Hållfasthetslära

   Author : David Lindblom; [2021]
   Keywords : PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

   Abstract : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

4. 18. Hydrothermally carbonized wood as a component in biobased material for 3D-printing

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Matilda Hendeberg; [2020]
   Keywords : Hydrothermal carbonization; 3D printing; biobased materials; biodegradable;

   Abstract : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. READ MORE

5. 19. Simulation and Modelling of Injection Molded Components : Fiber Reinforced Polymers in Powertrain Mounts

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Hanna Jakobsson; [2020]
   Keywords : Material modelling; polymer composites; FRP; orthotropic; powertrain mount; vehicle engineering; Digimat; Material modellering; polymera kompositer; ortotropisk; motorupphängnig; Digimat;

   Abstract : Powertrain mounts' purpose is to mount the engine and the gearbox in the car. Besides that, it isolate the body from the powertrain movements and road excitation. The most common material in powertrain mounts bracket is aluminum but lately, fibre reinforced polymer (FRP) has been acting as a substitute for the aluminum. READ MORE
