I currently work at the Impact Engineering Laboratory, Solid Mechanics and Materials Engineering, Department of Engineering Science, University of Oxford. My current project aims to understand the influence of humidity and temperature upon the mechanical performance of carbon fibre composites. You are invited to look at my research papers for more details of my work.
The mechanical response of materials can be affected by how fast the loads are applied, how quick deformation occurs. For instance, polymers tend to be stronger at higher speeds of deformation than at quasi-static regime due to their viscoelastic nature. In my research, I investigate how different materials behave at quasi-static and at dynamic regimes. This information is later translated into mechanical models to help engineers to design real components.
My research is oriented to the study of composite materials for underwater and aerospace applications. During service conditions these composites will be subjected to humid environments. My current investigation aims to develop a constitutive model able to capture the effects of water uptake upon the strain rate dependent properties of composites. Previously, in my master thesis, I investigated the degradation of fracture toughness of an epoxy resin due to hygrothermal aging.
I like to be challenged by complex experimental setups. I have designed my own equipment (thermal chambers for in-situ testing) and experimental setups for micromechanical tests (micro compresion, tension and compact tension rigs).
