Abstract

In this master’s thesis, principal stress plots are implemented numerically in Rhinoceros. This should complement the existing analysis tools and support the engineer in the assessment of the load-bearing behaviour of a structure. In a first step, a "standalone" function was written in Python, which can visualise the principal shear forces, principal moments and principal normal forces independently in the form of flow and dash plots. Subsequently, the "standalone" was integrated into an existing working environment. For this purpose, the CAD programme Rhinocer-os 7 was used as the frontend, which interacts with the static software Ansys APDL as the backend via the open-source framework Compas FEA. This was done with the aim of taking a further step towards parametric modelling and analysis of load-bearing structures. The resulting workflow is tested for its functionality using several load models and structure geometries.

Subsequently, the results are checked for plausibility with the help of calculations in AXIS VM and the application is optimised. The implementation of new functions is completed by the addition of a visualisation of the shear force resistance. Finally, the application possibilities are shown and the necessary boundary conditions are explained.
