Primary research is the mathematical modelling of metallic materials. This involves the phenomenological characterisation of sheet metals coupled with the development of yield criteria and their evolution during forming operations.
Findings in this area are used in the optimisation of stretch forming and flexforming processes for the aerospace industry. The insights gained in material modelling are used to optimise forming process kinematics and tooling by employing both analytical and finite element models.
In addition to optimisation of current forming processes, research also includes development of new flexible/toolless metal forming processes.
He is also the founder and a Director of Lenis Aer.
