Engineering components require an optimization of design and manufacturing parameters to achieve maximum performance – usually involving numerous physics-based simulations. Optimizing these is a resource-intensive endeavor, though, especially in high-dimensional scenarios or for complex materials like fiber reinforced plastics. Surrogate models are able reduce the computational effort, however, data generation still proves be resource-intensive. Additionally, their data-driven nature may...

Fiber orientation tensors (FOT) are used as a compact form of representing the mechanically important quantity fiber in reinforced composites. While they can be obtained via image processing methods from micro computed tomography scans (μCT), specimen size needs to sufficiently small for adequate resolution – especially case carbon fibers. In order avoid massive workload by and evaluation when determining full-field FOT distributions plaque or part, e.g., comparison with process simulations,...

Abstract Fiber orientation tensors (FOT) are widely used to approximate statistical distributions of fibers within fiber-reinforced polymers. The design process components made such composites is usually accompanied by a virtual chain. In this chain, process-induced FOT computed in flow simulation and transferred the structural simulation. Within simulation, effective macroscopic properties identified based on averaged information contained FOT. Solving field equations simulations as well...

We propose and assess a new decomposition-based interpolation method on fourth-order fiber-orientation tensors. This can be used to change the resolution of discretized fields tensors, e.g., obtained from flow simulations or computer tomography, which are common in context short- long-fiber–reinforced composites. The proposed separates information structure orientation using parametrization is based tensor components unique eigensystem. To identify this eigensystem given absence material...

Wet Compression Moulding (WCM) provides large-scale production potential for continuously fibre-reinforced structural components due to simultaneous infiltration and draping during moulding. Due thickness-dominated of the laminate, comparatively low cavity pressures are sufficient - a considerable economical advantage. Similar other Liquid (LCM) processes, forming strongly interact process. However, degree is much higher in WCM, which disqualifies sequential modelling approach. This...

Preeminent weight-specific mechanical properties predestine fiber-reinforced plastics for application in structural components. Virtual manufacturing chains (CAE-chains) capture a multi-step process sequence by interlinking models with corresponding constitutive laws each step. In common numerical solving techniques, spatial discretization of governing equations yields discrete solutions. Since mesh type and fineness are usually problem-specific, mesh-to-mesh mapping must be embedded the...

Continuous-fibre-reinforced plastics (CoFRP) have drawn increasing attention as load bearing structures in weight-sensitive applications. Typically, their full potential only unfolds after careful adjustment to requirements. However, owing the multitude of adjustable material parameters, determining a robust optimum is still great challenge, especially when considering multiple cases. In extension existing approaches, this work proposes an optimality criterion (OC) based on principal stress...
