Inverse FE Modelling Algorithm

#InverseFE #Materials

We have developed an automated inverse FE modelling algorithm that can optimise material properties or other modelling input conditions to match experimental and computational results. Through a SIMPLEX algorithm, a specific modelling parameter is optimised until the response of the model matches the outcome of physical testing. This is extremely helpful in case where the behaviour of a specific component cannot be isolated from the response of a large and complex assembly.

This algorithm was primarily developed to determine the behaviour of biological tissues across a wide range of loading rates as described in the following publications:

This algorithm has also been used to derive bulk material properties of complex structures across strain rates, conductive thermal properties of materials across temperatures, loading that leads to specific types of failure of assemblies.
