RESEARCH
Strain rate dependency of materials
The mechanical response of materials can be affected by how fast the loads are applied, how quick deformation occurs. For instance, polymers tend to exhibit greater strength at higher deformation rates compared to quasi-static conditions due to their viscoelastic nature. We investigate the behaviour of different materials under both quasi-static and dynamic regimes. This information is subsequently incorporated into mechanical models to assist engineers in designing real-world components.
Ageing of composite materials
During service, composite structures are subjected to various environments that may involve humidity or extreme temperatures. We develop experiments and constitutive models capable of capturing the effects of in-service conditions (e.g. water uptake and temperature) on the strain rate-dependent properties of composites (e.g. elastic/plastic properties, diffusivity, fatigue, and fracture).
Development of novel experimental techniques
We develope and design complex experimental setups. We have designed and built bespoke equipment (thermal chambers for in-situ testing) and experimental setups for micromechanical tests (micro compresion, tension and compact tension rigs).
Compression performance of composites
Fibre composites have significant potential in compression. Enhancements in their matrix, fibres, interfaces, and architecture can prevent or delay instabilities that cause failure in compression. Within the NextCOMP project, we have developed a series of multi-scale testing methodologies and protocols.
