Virtual Process Chain

The SIMUTENCE Virtual Process Chain starts with the definition of a concept and results in an optimized final part or assembly. Beginning with the design of a component, we include process simulations to virtually predict manufacturability as well as relevant manufacturing effects, such as fiber orientation distribution.

Based on this, manufacturability can be virtually assured, therefore-required process parameters can be determined and prediction accuracy of subsequent simulation approaches is gained. Finally, warpage and structural analysis is applied to assure dimensional stability as well as the fulfillment of load requirements. The steps of the Virtual Process Chain is based on a neutral exchange format, which enables to link different software packages.



The smart application of fiber-reinforced composites and hybrids requires material-specific design as well as the consideration of manufacturing effects. We offer the design of individual lightweight structures, including the application of design optimization for e.g. the topology of rib structures, the layup sequence of laminates or local reinforcements.



Process simulation enables the virtual validation of manufacturability as well as the prediction of manufacturing effects. Our process simulation approaches for forming and molding processes cover relevant large-scale production of composites and hybrids are based on high fidelity add-ons for commercially available software like Abaqus and Moldflow. This enables to enhance the modeling capabilities of existing software architectures.



Manufacturing of fiber-reinforced composites and hybrids is often accompanied with warpage due to thermal expansion and shrinkage. Thermomechanical analyses enable to predict dimensional instabilities and residual stresses. Our approaches cover fiber-reinforced thermosets, thermoplastics and according hybrids, under consideration of manufacturing effects predicted by process simulation.



The final part needs to fulfill load requirements, which can be virtually assured by structural analyses. The structural behavior of fiber-reinforced composites is distinctively influenced by manufacturing effects. Our Virtual Process Chain enables to consider these manufacturing effects in structural analyses, which guarantees reliable and robust part design.
