1. Development of thick GaN and AlGaN drift layers for vertical power devices
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.

2. Influence of hydrogen and carbides on high temperature cracking in cast Inconel
University essay from Uppsala universitet/Tillämpad mekanikAbstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

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. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

5. Fracture mechanics and damage modeling of injection molded high density polyethylene
University essay from Lunds universitet/HållfasthetsläraAbstract : For many applications a fracture is a disaster, leading to failure of the application and thus its usefulness. However, when it comes to the opening of a food and beverage package, fracture is a necessity. At Tetra Pak, food and beverage packages are produced to make food safe and available everywhere.
