Analyzing the flaw-tolerance of topology-optimized parts using fracture mechanics is becoming increasingly important as topology optimization gains wider industrial adoption and is used in the design of more structurally critical components.
In this presentation, I will share an example of optimizing a part using nTop and then Abaqus to verify the flaw-tolerance of that part. I will discuss how nTop’s ability to convert topology optimization results into CAD bodies enables the subsequent partitioning and meshing in Abaqus required to make accurate fracture mechanics calculations.
- Topology optimization can help engineers realize significant weight savings in load-bearing components.
- Applying fracture mechanics to topology-optimized parts is necessary to verify flaw-tolerance for structurally critical applications.
- The nTop can convert topology optimization results into CAD bodies, enabling efficient partitioning, meshing, and analysis of cracks using Abaqus.
