From Composites Design to Production with Altair HyperWorks

This webinar presents a complete composites workflow for all industries, the simulation-driven design workflow allows for an efficient process that enables time and money reduction.

In this demonstration, you will learn about efficient design and post-processing of complex laminated composite structures.

In this demonstration we show the full process of manufacturing injection molded parts to component performance in virtual process. The outcome is injection molded parts with desired mechanical performance with minimal experimental testing.

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.

Composite Pressure Vessels (CPV) play an important role in the emerging market for the fuel cell electric vehicles, but there are also numerous more traditional application areas for CPVs. The filament winding process used for the manufacturing of CPVs ties the possible fiber paths to the manufacturing process. Hence, in the design and analysis of CPVs it is important to include both the manufacturing and structural simulation. The webinar shows how Altair software interface with third-party filament winding simulation software to create CPV structural models using different level of details according to analysis needs. The use of multiscale material modeling provides means for accurate damage and failure predictions of CPVs.

3D printed lattice structures increase the design freedom in areas of the design where, for example, the full stiffness of the material is not needed, or a specific anisotropic material behavior is beneficial. At the same time the high geometric complexity on a scale below the standard modelling element size makes it extremely difficult to include all anisotropic effects in the standard CAE model and keep the same numeric efficiency together with the same accuracy of results. Using multiscale approaches like Altair Multiscale Designer to link microscale geometric features with a standard macro CAE model combines both scales in a highly efficient way and enables the numeric efficient and highly accurate simulation of lattice structures on component and assembly level.
