Numerical and Mathematical Modelling

 

This activity provides a model base for our research portfolio and is complimented by other modelling approaches such as mathematical modelling and semi-empirical design models. This research aims to integrate meoscale, atomic-scale and continuum models. Finite element models based upon the generation of residual stress, contact mechanics, and surface engineered components represent some of the themes of this activity. Static, dynamic, and non-linear programming therefore forms a part of this activity. Lagrangian, Eulerian, and Combined Lagrangian Elerian (CEL) models underpin the investigations of these highly nonlinear problems with an aim to integrate this modelling approach with Molecular Dynamics Simulations (MDS).
