Modal analysis - windmill assembly
A modal analysis is performed for two reasons. Initially it can be used as a model check to make sure proper connectivity in the FEM. But the main reason is to check for the natural frequency to make sure the part/assembly is not experiencing resonance. In this case, the windmill assembly was redesigned to increase the stiffness and prevent resonance.
static analysis - cylinder with internal pressure
A static analysis using FEM is a good way of running multiple designs and boundary conditions to see which is optimal for your design or re-design. In this case, the pressure in the cylinder was increased and a model was run to see if both the displacements and stress met acceptable criteria.
plasticity analysis - wheel with pressure and radial loads
A plasticity analysis using FEM is a good way of finding what the true capability of your design is. It is effective also for predicting test of a part to failure. In this scenario, the wheel was run to a higher pressure and the plastic strain was observed to be lower than the max criteria.
