Flow over a bicycle

Objective: Simulating a sphere pressing a flat plate and observing the plastic deformation in the plate. When the sphere is pressed onto the plate, the plate material will yield under the force applied on it due to the sphere being pressed into it. Once the sphere is retracted, the plate will undergo minute elastic spring…

Objective: Simulating the bending of a wire made of different materials and comparing the stress and strains developed in the wire. Materials: The wire materials compared are copper alloy, aluminium alloy and magnesium alloy. All of these are taken as non-linear material models (bilinear isotropic hardening models) so…

Objective: Simulating the rolling process of a copper alloy sheet between two steel rollers. Rolling is the process where a sheet is plastically deformed due to forces applied by two rollers and is a form of cold working process, i.e. plastic deformation is carried out below the recrystallization temperature of the sheet…

Objective: Computational modelling and stress analysis of weld joints for their verification in a component and comparing the results for different weld materials. Simulation parameters: Mesh: Since we want to verify the weld joints in the component, the mesh on the welds should be refined. The weld mesh is refined using…
