De Ruiter, T.M.H. (author)Research shows that the fatigue strength of a Very High Strength Steel (VHSS) can be significantly negatively effected by welds in a structure. The fatigue lifetime may be extended after cracking occurs by means of fatigue crack repair. A better insight by means of Finite ElementModelling (FEM) can help in understanding the effects of a repair...master thesis 2017

Slachter, E.G. (author)The Circumferentially Notched Tension (CNT) specimen is a potential candidate for determining the fracture toughness of highly constrained cracks, theoretically approaching plane strain conditions, even for small test specimen dimensions. This research aims to experimentally evaluate the use of the CNT test specimen geometry to fracture...master thesis 2016

Wijdeveld, W.K. (author)The European Commission proposed to increase recycling of packaging to 80% by 2030. This undermines the goal of a resource efficient Europe, because this may lead to the substitution of flexible packaging with the relatively easy to recycle rigid packaging. Developing a feasible method to separate materials in flexible packaging can contribute...bachelor thesis 2015

Zeng, Y. (author)For the industry of pipe-laying, the propagation of a crack can finally lead to failure of the structural components. This may cause catastrophic consequences for environment, economy and even lives of people. Therefore, the mechanical assessment of crack-like defects is of great importance in engineering practice. For non-linear problems,...master thesis 2015

Shakerifard, B. (author)This thesis is about the characterization of the microstructural cracks by the EDS and EBSD technique. This investigation has been done by depostion a layer of Ni-base alloy and then a C-Mn steel layer in order to understand the physial and chemical compatibility of these two dissimilar materials. This project is designed based on the welding...master thesis 2014
