For addressing the need to design components with better performance, we offer specific tests to better describe sheet formability at room and high temperature an reproduce part performance in FE codes, coupling micromechanical characterisation with macroscopic tests.

Forming limits evaluation at room and high temperature

High temperature FLC characterisation

Biaxial tensile test at room temperature

Deep drawing test
Edge cracking

Edge cracking modelling and prediction
Simulation by FEM of sheet forming operation to accurately predict edge cracking failures. A methodology has been defined to apply the ductile damage model implemented in the commercial software ABAQUS on the edge cracking prediction. An energy-based failure criterion based on the EWF tests is implemented in the model.
Modelling of part performance

Modelling of part performance (crashworthiness)
H embrittlement

Modelling of H embrittlement
Coupled diffusion-structural FEM able to estimate the hydrogen concentration distribution into structural components of AHSS. This model considers the principal factors influencing the hydrogen migration in stressed components and it is implemented in the commercial FE software Ansys Mechanical for its use in industrial applications.
Material data for modelling

Smart material data characterisation

Post necking behaviour and fracture strain for anisotropic behaviour
