Continuum Damage Mechanics (CDM) modelling of dislocation creep in 9-12% Cr creep resistant steels
… based dislocation creep model using the Continuum Damage Mechanics (CDM) approach. A dislocation CDM model was developed and implemented in the current work for uniaxial creep loading using the numerical modelling software Matlabᵀᴹ. The CDM approach was built upon fundamental dislocation …

Analysis of laminated architectural glazing subjected to combined wind and debris impact loading
… studying the stress response, failure and damage analysis of rectangular laminated architectural glazing against combined wind and windborne debris impact. Here both small-hard (like roof gravel) and large-soft (like timber) windborne debris are considered. The stress response of the …

Energy and Thermodynamically Based Approaches for Analysis of Damage in Contact Problems
<p>A novel methodology for analysis of damage in contact problems in presented. Two important categories of contact damage are studied, namely crack nucleation and adhesive wear. The proposed methodology is primarily based on the laws of energy and thermodynamics, and as such offers great …

Continuum Damage Mechanics to Model Glulam Beams Reinforced with Glued-In Steel Cables
This study aims to investigate the use of Continuum Damage Mechanics (CDM) for the computational modelling of timber, a material known for its high variability and anisotropy. Timber has not had a standard way of performing computational mechanics like that of steel and concrete, which has made …

Progressive Failure Analysis of Laminated Composite Structures
… includes both initiation and propagation of damage. In this work a progressive failure methodology is developed and implemented in the commercial Finite Element software package, Abaqus. Out of the numerous failure criteria available in the literature to study damage initiation and …

Coupled Gradient Enhanced Damage - Viscoplasticity Model Using Phase Field Method
… is developing a framework to describe damage evolution as a phase transformation in solid materials and couple it to the well-known Perzyna type viscoplastic model to account for inelastic behavior of ductile materials. To accomplish this task, the following steps have been performed. …

Multi-Scale Physics Based Modeling of Tire Rolling Resistance Considering Aging
… Additionally, the dissertation strove to build a continuum damage mathematical model using a combined testing/modeling methodology to predict the aging of Styrene-Butadiene Rubber (SBR) after continuous exposure to the atmosphere. The obtained model was developed through the implementation of …
