Modelling of structures and behaviour laws
The modelling process uses tools such as finite elements to model the response of a mechanical system or material. Our field of expertise ranges from static to dynamic including thermomechanics.
The following are examples of simulations applied to tensile tests of a notched specimen. They are used for the identification of a ductile failure model or for a sheet metal clamping device.
Impact modelling with ductile tearing :
We use LS-DYNA software for mechanical simulations, with expertise in the following areas
Shaping calculations with anisotropy.
- Identification of Johnson-Cook or MMC (Modified Mohr Coulomb) type rupture models, applied for example to the simulation of the perforation of sheet metalwood sandwiches and identification of hyper-elastic behaviour models, for example Ogden type for elastomers.
- Crash calculations on structures.
- Optimisation of mechanical parts via morphing or topological operations.
- Calculation of composite structures.
Here are some examples of numerical calculations made with LSdyna on the modelling of shaping process, impact, and crash process on structures :
Calculation – structure
Calculation - forecast of rupture
Identification of behavioural models for very large deformations
Calculation - thermal expansion
Sizing a load cell
Topological optimisation of a jaw for shear tests
