Calculation of short fibers orientation on a finite element model reduced by algorithms for topological optimization of structures

The paper proposes a methodology for calculating the short-reinforced thermoplastic materials molding on elements of a topological optimization mesh, without the use of three-dimensional geometric models. The orientation of the reinforcing fibers on the mesh elements of the topological bracket optimization is calculated. The results of molding modeling on directly imported mesh are compared with the simulation results on the three-dimensional geometric models synthesized by the results of topological optimization. It is shown that the developed technique allows to significantly reduce the design calculation time for power structures molding. The presented methodology for calculating hydrodynamic problems on elements of topological optimization mesh is easily formalizable and can be implemented in batch mode based on API system interfaces, which makes it possible to solve the problems of hydrodynamics and determining the tensor of fiber orientation at internal iterations of the topological optimization cycle.
