1. Exploring the interactive effects of light intensity and pH on coral oxygen production
University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskapAbstract : The study aimed to explore the possible interaction between acidification and light intensity and the effects on corals' oxygen production. Interactions between temperature and pH have been thoroughly researched and proven to cause immense stress on the world’s reefs. READ MORE

2. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth
University essay from Karlstads universitetAbstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE

3. Life and fracture in very high cycle fatigue of a high strength steel
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

4. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications
University essay from Linköpings universitet/Mekanik och hållfasthetsläraAbstract : In the transition from conventional to green energy production resources, steam turbines are used to satisfy the lack of energy during peaks in the demand times and the limited access of renewable resources. This type of usage for steam turbines makes them operate on a flexible schedule, which leads to unpredictable issues related to shorter component life and faster crack propagation. READ MORE

5. Estimation of Fatigue Life for Welded Gears Using LEFM
University essay from KTH/Hållfasthetslära (Avd.)Abstract : The aim of this thesis is to estimate the high cycle fatigue life of welds using finite element methods and liner elastic fracture mechanics (LEFM). Develop a new method of calculating the fatigue life that can replace the old method in use today at GKN Driveline. This is a continuation of an earlier master thesis1. READ MORE
