AlphaCell for quick and accurate sound package design 

Vibro-Acoustic Response of Multi-Layer Systems: Creating a Condensed Model to Reduce Mesh Size and Calculation Time
A possible way of reducing the calculation time and mesh size in vibro acoustic response is to condense the description of multi-layer plates into a single, equivalent plate representation. The plate is then modeled using frequency dependent parameters in visco-elastic models. The webinar will present several representations of this approach applied to constrained layers, multi-layer plates as well as ribbed and stiffened plates.

Webinar: Auralization Features of AlphaCell - Listening to the Efficiency of the Materials
The examples presented during the webinar will cover the cases of sound absorption and sound transmission.

Quieter Products Using OptiStruct & AlphaCell: The Right Effort with the Right Tool
This webinar will present the basics of porous material modeling and user key benefits of a combined usage of OptiStruct and AlphaCell. Please note: You will need to login to Altair Connect to view this recording.
