The objective of this thesis is to achieve an interaction of yarns of a rope with each other, to gain an understanding of tensions and contact situations and to calculate stiffnesses. For this purpose a geometric model of a semistatic Kernmantle rope is developed and an analysis based on the finite element method (FEM) is carried out. The rope piece consists of a core made up of twisted adjoining yarns and a braided sheath. Kernmantle ropes are characterized in that the core absorbs most of the stress and the sheath protects the core from abrasion and other environmental impacts such as UV radiation. The material used is polyamide 66 which belongs to the group of semicrystalline thermoplastics. As it is not possible to form such a tightly braided structure in a CAD application, the FEM is used. Due to the malleable material behavior single yarns were compressed to rope lines which in turn were compressed to a core by placing them next to each other. Then the sheath could be placed over the core and pressed on the core with the same malleable material behavior. Due to the large deformations and the high number of contacts between the elements an explicit calculation process with a better convergence behavior was used for the geometric structure and the FEM result evaluation. By comparing the kinetic energy with the strain energy a quasi-static simulation could be performed despite the dynamic calculation process by minimizing the kinetic energy. After completing the geometric structure by using the FEM a tensile strain was applied to the frontal area of the rope piece and exerted with elastic material behavior. The bending strain was also considered to develop possible ideas for even more realistic stresses in models. Local tensions and the deformation behavior of the rope piece were explained and analyzed. By compressing the geometry an adjoining geometry could be created that resembles a real Kernmantle rope. In conclusion it can be said that this model can serve as starting point for more complex calculations.
