Week 5 Sphere pressing on a plate

Objective:

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…

Week 2 Bevel Gear Challenge

Objective:

Grid dependency test: It is a type of parametric study of a finite element model where the variation of the analysis results is observed with respect to changing mesh refinement (i.e. reducing mesh element sizes). In other words, the dependency of the FE analysis on the mesh applied is studied. At the point where the FE…
