This addition will enable aerospace engineers to save time for testing & material model calibration.

e-Xstream engineering, an MSC Software company, announces that a new version of Digimat, a nonlinear multi-scale material and structural modeling platform, now integrates NCAMP and AGATE data as ready-to-run progressive failure models for unidirectional and woven composite, for various conditions in the Digimat-MX database.

“Nine AGATE and seven NCAMP materials are already available in Digimat, including both unidirectional and woven fiber forms, and more will continue to be added in the future,” said Rachael Andrulonis from Wichita State University’s National Institute for Aviation Research (NIAR).

Digimat users can directly perform predictive structural analysis with the reference NIAR grades for stiffness, as well as for progressive failure.

Currently, all AGATE and NCAMP materials in Digimat contain an epoxy matrix. These materials contain either carbon or glass fiber and multiple weave types, such as 8-harness satin, 5-harness satin and plain weave. The resin systems include the following epoxy matrices: 2510, 7740, E765, 8552, MR60H, 5320-1 and MTM45-1. The fiber types include the following: glass fiber - 7781 and 6781 S2; carbon fiber - T650, T700, NCT321, T300, AS4, NCT4708, IM7-G, and HTS40.

“Over the last 2 years, we’ve been partnering with NIAR to develop, verify and validate the Digimat Virtual Allowable platform. Today, we are pleased to release Digimat material models of the composites available in the NCAMP & AGATE. I’m sure that these models will be of great use for our composites customers across the aerospace industry," said Dr. Roger Assaker, CEO of e-Xstream engineering and Chief Material Strategist of MSC Software.
