1. Damage based constitutive model for predicting the performance degradation of concrete
An anisotropic elastic-damage coupled constitutive model for plain concrete is developed, which describes the concrete performance degradation. The damage variable, related to the surface density of micro-cracks and micro-voids, and represented by a second order tensor, is governed by the principal tension strain components. For adequately describing the par

2. Aplicação da Teoria de Dano na análise do comportamento de materiais compósitos / Aplicação da teoria de dano na análise do comportamento de materiais compósitos
A Mecânica do Dano Contínuo (MDC) teve importante desenvolvimento desde os trabalhos iniciais de Kachanov e Rabotnov sendo uma ferramenta prática para considerar processos de danificação em materiais e estruturas em nível de contínuo macroscópico. Neste trabalho, apresenta-se uma aplicação da teoria do dano anisotrópico baseada em teorias desenvol

3. THE STRUCTURAL BEHAVIOUR OF COMPOSITE LAMINATES MANUFACTURED USING RESIN INFUSION UNDER FLEXIBLE TOOLING
This thesis presents a detailed investigation on the structural behaviour of hybrid plain weave composite laminates manufactured using Resin Infusion under Flexible Tooling (RIFT) process under static and dynamic impact loading conditions. Composite laminates were manufactured using a newly developed RIFT manufacturing facility marking the beginning of a new

4. Recombinant superoxide dismutase reduces oxygen free radical concentrations in reperfused myocardium.
It has been proposed that oxygen free radicals mediate damage that occurs during postischemic reperfusion. Recombinant human superoxide dismutase (r-h-SOD) has been shown to be effective at reducing reperfusion injury, but it is not known if this infused enzyme actually reduces oxygen free radical concentrations in the myocardial tissue. Electron paramagneti
