A Non-linear Visco-elastic Model for Dynamic Finite Element Simulation of Bovine Cortical Bone
Modelling and simulation of the human body during an impact situation such as a car accident, can lead to better designed safety features on vehicles. In order to achieve this, investigation into the material properties and the creation of a numerical model of cortical bone is needed. One approach …

The effect of very high hydraulic pressure on the permeability and salt rejection of reverse osmosis membranes
… - likely due to membrane compaction. A simple visco-elastic model was shown to be able to model the overall shape of the permeability curve in time. However, this model does not match the data well when pressure is removed and then reapplied. From the perspective of membrane performance, RO is …

Digital Mix Design for Performance Optimization of Asphalt Mixture
… contacts and local stability. A simple visco-elastic model was applied to model the contacts between asphalt binder and aggregates. The surface texture of an aggregate particle can be taken into consideration in the inter-particle contact model. The void content before compactions was …

Mechanical behaviour of Clay-Shales (Argille Scagliose) and implications on the design of tunnels
… quantification and prediction of the models of behaviour associated with them. In particular, during the last few years, two Research Programmes on these topics (“Tunnelling in difficult conditions” and “Mechanised excavation of tunnels”, co-ordinated by Professor Giovanni Barla) were …
