Preloaded bolted connection failure

Multiphysic simulation of a fusible part. An electric potential is gradually applied at each extremity of the plate. The joule heating effect will cause an temperature increase and an elongation of the part. When it reach the cylinder, there is a short circuit wich cause local high temperature wich erode the plate.

Simulation of impact protection structure with LS-Dyna. SPH elements are use to simulate the impact mass. Rendering is done with Paraview.

DEM-FEM coupled simulation of impact stress and strain in a convoyeur chute.

It is a impact simulation on a roof under high velocity. The result was rendered in Paraview 5.8.

CFD simulation of water exiting dam gates. Visualisation is done at alphe 0.5. More than 250 000 m^2 of surface. Less than 2 days of calculation on our server.

Multiphysique simulation with LS-Dyna. Liquid is modeled with SPH and the protective screen use finite element with material plasticity. Dynamic relaxation and explicit solver are used. Older industrial sites have storage tanks near civilian facilities. Risk analyzes concerning this equipment may no longer meet current safety rules. This simulation present a scenario of failure in the shell of a storage tank and a civil protection structure.

Simulation of a bicycle wheel with disc brake. The colors on the surfaces are for pressures and those on streamlines represent the velocity of the air. Performed with OpenFOAM in steady state and MRF are used. Flow velocity = 50 km/hr Force with disc brake = 1.35 N Cd with disc brake = 0.03 Force without disc brake = 1.16 N Cd without disc brake = 0.026 Simulation d'une roue de vélo avec le frein à disque. Les couleurs sur les surfaces représentent les pressions et celles des lignes de courant représentent les vitesses. Réalisé avec OpenFOAM en régime stationnaire et avec plusieurs domaines de référence (MRF). Vitesse de simulation = 50 km/hr Force avec le frein à disque = 1.35 N Cd avec le frein à disque = 0.03 Force sans le frein à disque = 1.16 N Cd sans le frein à disque = 0.026
