Project
Profile
Accelerated Insertion of Materials - Composites |
Customer:
Boeing, DARPA
Engineering
Services: Software development, material property prediction
and synthesis, knowledge base development.
Project Dates:
2001 - present
Summary:
To address the need for reduced insertion time of new
materials, MSC is developing and demonstrating computational
simulation tools for quickly and reliably predicting the thermo-physical
and strength properties of composite materials. As a subcontractor
to Boeing on this DARPA (Defense Advanced Research Projects Agency)
program titled "Accelerated Insertion of Materials", MSC
is focusing on using analytic methods to reduce the time needed
to introduce a new composite material system into products.
Tools Developed:
MSC developed a series of Mathematica packages that go from
micromechanical analyses of composites to structural subelements
of an aircraft. A major goal of the program was linking all levels
of these analyses together. The Mathematica language is ideal for
developing data structures such that the output from one operation
directly becomes the input for the next.
In addition
to the Mathematica packages, MSC has developed standalone applications
to compute structural mechanics problems for composite materials.
These tools are currently being used as part of the AIM-C architecture.
Some examples
of output are shown on the following two figures.
