Software Development Metal Forming Simulations

METAFOR : an object-oriented Finite Element code for the simulation of solids submitted to large deformations

2D/3D elements (large strains). Implicit/explicit time integration (HHT, Chung Hulbert, …) Thermomechanical coupling (staggered or fully coupled schemes). Frictional contact between deformable bodies or analytical surfaces. Arbitrary Lagrangian Eulerian formalism. Meshing and remeshing procedures. Large set of constitutive laws (thermo-elasto-visco-plastic, damage, …) Crack propagation (erosion method).

Biomechanics

Brain Model Unstructured FE mesh generation from medical images (MRI scans). Simulation of neurosurgery (brain shift / tumor resection). Simulation of injuries (head impact).
