Crack growth analysis

I could write a simple script to model crack growth and failure through a structure. It would be based on an evolutionary algorithm similar to the topology optimization script. Contact me if you think this is something worth pursuing for your needs.

Fatigue analysis

I plan to develop a very basic fatigue analysis script to integrate with CalculiX. The basic fatigue analysis capability will use Miners Sums and Fatigue Diagrams methods. Essentially all it would need is a simple block load history alongwith the material endurance limit and slope of SN curve.

Substructure analysis

I could develop a substructure module that can extract internal forces from an assembly model for you to directly apply to a breakout component model. This can save you enormous solve time as you only need to build a coarse model of a large assembly.

With the substructure program you would be able to extract all the internal forces acting on any cross-section in the assembly model. These internal forces can then be directly applied to a finer meshed component model to get an accurate picture of what is going on locally.
