Biography
Akash's research focuses on better understanding the mechanical properties of low-impedance polymers and their composites, specifically the response to high rate deformations, such as those experienced in impact loading scenarios. He does this by developing new methods for experimentally measuring the response of polymers and composites under challenging loading conditions, and for modelling and designing polymer structures.
These materials are widely used for energy absorbing applications in industries as diverse as automotive, aerospace, manufacturing, biomedical, defence and consumer goods. However, their behaviour during impact is not well understood, which prevents the optimisation of material properties and structural design.
Research Interests
- Experimental mechanics and novel technique development
- Thermo-mechanical characterisation
- High rate experiments of low-impedance materials
- Impact behaviour of polymers and their composites
Current Projects
- Impact modelling of polymers, high rate experiments for solid-state simulations: Gaining a deeper understanding into the impact response of high-performance polymers and composites in order to provide design guidelines for producing polymer systems optimised to work efficiently in different impact applications.
