Analytic sizing

We believe that for most composite structures it is beneficial to perform an analytic sizing hand in hand with the design prior to FEM calculation. This improves understanding and simplification of load paths and yields a fiber-appropriate and cost-effective design. Analytic sizing is done using Jupyter Notebooks in conjuncture with git to allow version control. We have an extensive code base which we adjust rapidly to fulfill your needs.

We perform:

• Analytic structural strength calculation according to engineering standards
• Analytic static stability analysis (buckling)
• Composite fatigue analyis (linear fatigue accumulation)

Topology Optimization

Our topology optimization software CMTop is capable of generating robust compliant mechanisms for motion and deformation control. It incorporates stress constraints, robust design with respect to manufacturing uncertainties and various objective functions (Force Inverter, Path generation, Compliance minimization). A nonlinear finite element solver, the latest filter and projection methods and stress constraints are featured. Furthermore, manufacturing uncertainties can be considered during optimization.

In the project MILAN, the software has been used to generate compliant mechanism stacks for the precise deformation of a morphing wing leading edge. But many other applications are conceivable – like Micro-Electro-Mechanical Systems (MEMS), robots, packaging and medical devices.
