Research Interests
Identifying the correct modelling parameters to reproduce experimental results can be a difficult problem. If the number of parameters is large then it is often not possible to analytically determine which values will give the optimum fit. A genetic algorithm developed by Dr. Charles Mareau is currently being used in order to determine parameters for an Elasto-Plastic Self-Consistent (EPSC) model. The experimental data to be reproduced includes tensile and compressive macroscopic stress strain curves in the transverse, rolling, and normal directions of the material, several lattice strain curves measured both parallel and perpendicular to the applied load, and the Lankford Coefficients for the three directions in both tension and compression. By attempting to simultaneously fit the model results to all of these different experimental datasets it is hoped that a single set of parameters which best represents the overall physical behaviour of the material can be found.
