SANTA ANA, Calif. -- October 30, 2012

MSC Software Corporation, the leader in multidiscipline simulation solutions
that accelerate product innovation, today announced that Stanford University
is using MSC Nastran and Marc to conduct a groundbreaking study on the testing
and analysis of complex composite materials. The goals of the study are to
reduce extensive and expensive testing programs, optimize the design of
testing configurations and redefine structural deformation and failure
processes. The sophisticated analysis capabilities of MSC simulation solutions
are being used to predict the failure characteristics of heterogeneous
composite materials to a greater degree and explore the possibilities of
further innovation.

Traditional modeling of heterogeneous composite materials is almost always
based on some degree of homogenization, taking materials with diverse
characteristics and modeling them for evaluation based on materials with
similar characteristics. Professor Tsai, Professor Research Emeritus in the
Aeronautics and Astronautics department at Stanford University, and his team
are using Mesomechanics to recognize local heterogeneity of composite
laminates to build more accurate 2D shells and 3D solid models. Specialized
composite analysis capabilities within MSC Nastran and Marc address the
failure characteristics of the models. Preliminary results of the new method
have been positive when it was recently applied to the novel bi-angle NCF (non
crimp fabric) tape. Bi-angle NCF is a revolutionary lightweight material with
strength equal to carbon materials and up to 30% lighter. The orientation of
layers that makes BI-angle NCF unique was modeled, efficiently pre-processed,
and analyzed with MSC’s simulation solutions to optimize the manufacturing

“We have found that MSC Software’s solutions have the combination of technical
depth and ease of use,” said Professor Tsai. “They made our challenge
solvable. We are very pleased to be able to learn more about our problem and
will continue to explore next steps.”

“The need for lighter weight and stronger materials that have predictable
behaviors is growing dramatically as a result of the greater demands for
improved vehicle fuel efficiency and safety,” said Dominic Gallello, President
& CEO of MSC Software. “Dr. Tsai has been a pioneer in this field and we are
delighted to collaborate with him in this important project.”

With recent advancements in heterogeneous materials, it is becoming more
critical to have physical and geometric models that better represent these
complex materials. When analyzed, these models would provide a far more
accurate evaluation of how heterogeneous composite materials will behave in
real-life environments.
