Availability of material data is a major bottleneck in simulating composite structures. Material suppliers’ datasheets or handbook values do not represent the actual properties resulting from the company’s manufacturing processes. On the other hand, doing a complete material characterization through a test campaign is very costly and time consuming.
To overcome these issues, accurate multiscale simulation with predictive capability, as provided by Altair Multiscale Designer, can be used in combination with a limited set of physical tests for developing accurate material models. Further, the accurate modeling of the composite nonlinear and failure behavior through the multiscale approach brings the accuracy of composite structural simulations to a new level.
