Influence of geometric imperfections and increasing turbine sizes on validity load transfer functions in bolted ring-flange connections

The global focus on climate change and the transition away from fossil fuels has highlighted the importance of renewable energy sources. Offshore wind turbines are being optimized and are therefore growing in size and power. <br/><br/>This research focuses on bolted ring-flange connections, a connection type that plays a crucial role in the...

Determination of planar crack front geometry based on near-crack surface displacement field obtained from simulated digital image correlation measurements

Digital image correlation (DIC) is a surface measurement technique that can be applied whilst performing experimental tests. At Delft University of Technology, a fatigue test is to be conducted and DIC will be used to measure surface displacements around the developing crack. These surface displacements are directly related to the crack geometry...

Strain Rate Dependen 3-Point Bending Test and Simulation of a Unidirectional Carbon/Epoxy Composite

In order to use composite materials in automotive production while ensuring that passengers safety it is crucial to fully understand the strain rate effect on their mechanical properties.This study implements a strain rate dependent 3-point bending test setup for a high rate servo-hydraulic testing machine. A finite element model to simulate...

Modelling and simulation of bone implant healing

In this report a model for the ingrowth of a prosthesis in a bone will be formulated and simulated. First an overview is given of all the biological processes that are part of this healing process and what external factors can influence this process. Then a first mathematical model is presented in which the mechanical stimuli (one of the...
