A new biomechanical model for understanding aging of stored Red Blood Cells. This project plans to develop a novel modelling framework to accurately represent the biomechanical properties of red blood cells (RBCs) over time under stored conditions. Stored RBCs suffer ageing-related deformability changes which impede RBC functions.

This project plans to develop a novel modelling framework to accurately represent the biomechanical properties of red blood cells (RBCs) over time under stored conditions. Stored RBCs suffer ageing-related deformability changes which impede RBC functions. The framework aims to integrate models for RBC membrane, inside haemoglobin and outside storage solution, and accounts for ageing effects by embedding time-dependent correlations. It should provide new insights and understanding of the mechanisms of deformability changes of RBCs during stored lifespan. Therefore, it should significantly improve blood storage industry practices in terms of improving RBC storage protocols with preventative ageing strategies.Read moreRead less

A Novel Failure Approach for Multi-stage Aluminium Sheet Forming. This project aims to reduce waste in the production of aluminium cans. Over 200 billion aluminium beverage cans per year are produced worldwide (including 30 billion in Australia), but there is a problematic level of waste due to aluminium sheet forming failure.

This project aims to reduce waste in the production of aluminium cans. Over 200 billion aluminium beverage cans per year are produced worldwide (including 30 billion in Australia), but there is a problematic level of waste due to aluminium sheet forming failure. Current simulation of a multi-stage sheet forming process for rigid-packaging components results in a higher rejection rate due to the inaccuracy of conventional forming and fracture limit models. A novel development in this work is the design of a nonlinear strain path which is intended to maximise the forming limit of aluminium alloys and also estimate the safety margin up to the necking or fracture limit in the early die design stage.Read moreRead less
