Computational Solid Mechanics – CSM

The CSM team aims to develop numerical methods, mechanical models and materials characterisation methods applied to solid mechanics problems.

In particular, the approach proposed here is to take an interest in the forming chain of parts or components to be able to predict and optimise in-service properties by integrating the thermomechanical history of the material. It is also often essential to integrate the organisation of biological tissues on a microscopic scale into our biomechanical studies, as this has a direct impact on their mechanical properties.

We are working on the development of advanced numerical methods in a demanding software environment. The algorithms and methods must fit into the context of complex software structures in commercial software. We are proposing new models adapted to the complexity of the load paths encountered in forming or to the variability of tissue properties in biomechanics. Materials characterisation also requires the development of unconventional test methods that are better suited than standard test benches to complex loading paths and semi-industrial or medical environments.

The areas developed by the team cover the following fields :

• Numerical modelling of forming processes
• Behaviour - damage - failure for complex loading paths
• Biomechanics
• Dialogue between tests - models - calculations, Inverse Analysis & Optimisation
• AI & Forming

Our expertise enables us to work on the development and modelling of various applications, including :

• Solid-state forming processes: forging, rolling, stamping, hot forming quenching, etc.
• Hybrid and incremental processes: flow forming, magnetic pulse forming, etc.
• Plastic deformation assemblies: from installation to mechanical strength (riveting, crimping, etc.)
• Support for the development of medical devices and surgical planning tools
• Induction heating
