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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license.
