Estimation of Fatigue Life for Welded Gears Using LEFM
, 2017 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.

BEM/OQM Formulation to Simulate Crack Problems
Trends in Computational and Applied Mathematics, 2008 Over the last few years the Boundary Element Method (BEM) has been successfully applied to linear elastic fracture mechanics problems (LEFM), involving static and dynamic cases. An approach to solve LEFM problems is presented in this work.

Shock and Vibration, 2014 During fatigue damage accumulation, cracks propagate through the material leading to catastrophic failure. As the cracks propagate, the natural frequency lowers, leading to a changing stress state.

Flaking of black anodic films in space environment: Ageing and numerical simulation [PDF]
, 2012 Black coatings can be used for managing passive thermal control on spacecraft and for avoiding stray light in optical equipment. Inorganic black anodizing of aluminium alloys is a solution to obtain films with a low outgassing and a sufficient thermal ...

Investigation of Crack Propagation in Asphalt Pavement Based on APT Result and LEFM Analysis
Journal of Testing and Evaluation, 2019 When reinforcing existing cracked asphalt pavements, the design and evaluation of the durability of the reinforced structure are quite different from those of a new pavement generally based on fatigue criteria deduced from stress and strain fields ...
