Ceramic matrix composites (CMCs) are advanced materials that consist of a ceramic matrix reinforced with a high-strength, high-stiffness material, such as carbon fibers. They offer excellent thermal and chemical stability while exhibiting low weight and exceptional mechanical properties. A novel CMC material is the C/C-SiC produced with 2/2...

Atherosclerosis is a lipid-driven inflammatory disease of the arteries. It causes<br/>increased thickness of the intima layer of an artery, due to build-up of, among<br/>others, lipid deposits. Eventually, this could cause rupture of the blood vessel’s<br/>wall, leading to thrombus forming and possibly to clinical events. Clinically, the<br/...

The pond is a low-lying ground intended to retain or detain both stormwater. In the past, building ponds was a common way to keep fresh water for livestock and irrigation. Due to the rapid urban development and the emergence of centralized water conservancy facilities, the traditional ponds have largely disappeared. One of the crucial examples...

This thesis contributes to the scientific underpinning of the battle against fruit frost. Fruit frost is the freezing damage to blossoms when in the growing season the night temperature drops below 0±C. This results in damaged or undeveloped fruits, and a yield loss for the fruit farmer. Several techniques against fruit frost have been developed...

Type IV composite pressure vessels (CPVs) are used commercially for the gaseous storage of hydrogen in fuel cell electric vehicles (FCEVs). However, their economic implementation requires material optimization and a reliable prediction of the vessel strength. In this regard, their burst when loaded under internal pressure is impacted by the...

Adhesively bonded joints have proven to outperform their mechanically fastened joint counterparts, as they present a more structurally efficient method of load transfer, lower stress concentrations and better fatigue performance at reduced weight. In the specific case of the Adhesively Bonded Single Lap Joint (ABSLJ), bending-induced stresses...

Miniaturization of spacecraft has been gaining wide interest in the space industry, given its potential for reducing space missions' costs and providing a novel approach to enhancing and facilitating spaceflight. Recently, a lot of research has been successfully put into this field along with the advancements that make it more feasible, though a...

Fascicle shear is theoretically a mechanism by which skeletal muscles lengthen. Existing ultrasound based techniques allow measurement of muscle architecture parameters, but not the quantification of shear strain. In this study, an algorithm that tracks the shear strain from ultrasound images using a continuum representation of the muscle was...

A series of accelerated corrosion tests were done by SGS INTRON (commenced by Combinatie Aanpak Maastunnel, constructor of the Maastunnel project) to investigate for a proper repair material for the deteriorated concrete floor in the Maastunnel at Rotterdam. Five types of fiber reinforced mixtures with different tensile behavior ranging from...

In general, damage models for Fibre-Reinforced Polymers (FRPs) can be divided into two categories: Continuum Damage Models (CDMs) and Fracture Mechanics Damage Models (FMDMs). Damage models within each of these categories are advantageous for different type of failure mechanisms. Therefore, it is of interest to develop a unified framework in...

Epoxy resins are increasingly used in critical structural components with widespread applications in the transportation, construction and energy industries. The wind energy sector is one of the fastest growing commercial markets for epoxy resins, meaning that the structural behaviour of epoxy resins is becoming a key area of research, especially...

Composite delamination represents one of the most critical failure mechanisms occurring in composite structures. In case complex structures are being designed, numerical methods need to be employed. One of the methods to numerically simulate delamination in a Finite Element environment is through the employment of the Cohesive Elements, which...

Composite structures are increasingly applied for their unique set of properties. However, their behavior is not yet fully understood, amongst others, due to complex interactions of failure modes. This research implemented a blended stress-strain and fracture mechanics based progressive damage analysis model, based on a Continuum Damage Model ...

Coppejans, Okko (author)
This master thesis is built up around two questions. First: Is it possible to calibrate a ductile failure model, where the strain at failure is a function of stress triaxiality and Lode angle, using only a single SENB specimen? The failure model that is referred to describes local failure in a finite element model to simulate ductile fracture....

Murugesan, Yaswanth (author)
Various contact mechanics theories have been developed in recent years. The most popular are the statistical asperity theories of the type of Greenwood and Williamson and Persson’s theory, which treats self affine rough surfaces. The latter theory includes roughness at all length scales as well as long range elastic interactions. However, it is...

A novel continuum damage mechanics model for 2D woven fabrics has been developed and implemented in a VUMAT subroutine for Abaqus/Explicit. The model takes into account the shear non-linearity, the toughening mechanisms associated to tensile failure, and the influence of shear stresses in the initiation and propagation of tensile damage. <br/>...

Despite great strides made in understanding and modelling Fiber-Reinforced Polymers (FRPs), their full potential is held back by the inability to accurately predict failure. Contrary to past attempts focused on isolated application of stress-strain and fracture mechanics based failure theories, this research builds upon the existing framework by...

Continuum manipulators are high degree of freedom structures that can use their increased degrees of freedom to navigate through an environment with obstacles. This type of manipulator is underactuated, which make them promising for adapting to their environments. However, current research is mainly focused on accurate positioning and obstacle...
