1. Fracture simulation with a hyperelastic phase field model
University essay from KTH/HållfasthetsläraAbstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

2. Experimental Testing of EPS-foam
University essay from KTH/HållfasthetsläraAbstract : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

3. Simulations of experimental crack development in ceramic material with notched specimen
University essay from KTH/HållfasthetsläraAbstract : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. READ MORE

4. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205
University essay from Jönköping University/Tekniska HögskolanAbstract : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. READ MORE

5. Fatigue properties of Laser Powder Bed Fusion (LPBF) built 21-6-9 stainless stee
University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)Abstract : Fatigue performance is one of the important mechanical properties which is hindering some of the additive manufacturing build structures. The main objective of this study is to investigate the fatigue life dependence of the 21-6-9 austenitic stainless-steel build using the laser powder bed fusion (LPBF) technique. READ MORE
