Pragmatic optimisation methods for determining material constants of viscoplasticity model from isothermal experimental data (2013)
Journal Article

A procedure to estimate material constants for the unified Chaboche viscoplasticity model from experimental data has been published elsewhere; however several critical assumptions are made to enable this and potential numerical problems can limit the...

Comparison of several optimisation strategies for the determination of material constants in the Chaboche visco-plasticity model (2013)
Journal Article

Determining representative material constant sets for models that can accurately predict the complex plasticity and creep behaviour of components undergoing cyclic loading is of great interest to many industries. The Chaboche unified visco-plasticity... Read More about Comparison of several optimisation strategies for the determination of material constants in the Chaboche visco-plasticity model.

Effective determination of cyclic-visco-plasticity material properties using an optimisation procedure and experimental data exhibiting scatter (2013)
Journal Article

It may be inevitable in the design and analysis of most high temperature components (such as power industry pipe work) that variations in load and/or temperature will occur in normal operation. This presents complications in the prediction of the res...
