06 Feb 2021 | Contributor(s): Nikki Huang

This presentation was given at Altair Virtual ATCx Composites: https://atcxcomposites.virtual.altair.com/. Variational asymptotic beam section (VABS) is a unique technology continuously funded by the US Army since 1988 and it has become a tool of choice in the helicopter and wind turbine...

iVABS

19 Nov 2020 | Contributor(s): Nikki Huang

iVABS (namely integrated VABS), is a design framework for composite slender structures (also called composite beams) such as helicopter rotor blades, wind turbine blades, high aspect ratio wings, bridges, shafts, etc. This framework bundles PreVABS, VABS, GEBT, Dakota, along with msgpi for...

PreVABS

16 Nov 2017 | Contributor(s): Nikki Huang

PreVABS is a pre-processing tool for VABS and SwiftComp. This tool is designed to reduce the workload of preparing input files of beam cross sections for VABS and SwiftComp, and to make the process automatic for the design and optimization purpose. Cross sections with general and...

Injection Overmolding Manufacturing Process Simulation

29 Jun 2017 | Online Presentations

Injection over-molding or hybrid molding is a high-rate composites manufacturing process for fabrication of structural components with complex geometries.  The structural backbone is provided by a continuous-fiber woven prepreg while the geometric complexity is realized via injection...
