Topology Optimization of Loaded Knee Structure with a Maximum Stress Constraint

Application ID: 75821

This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young's modulus otherwise used in the model. This combination is standard practice within the field of stress constrained topology optimization.

The model considers a standard benchmark problem with a stress concentration in a corner. To avoid a beam in pure compression at the load, an extra load case is considered.

This model example illustrates applications of this type that would nominally be built using the following products:
