New FEA Product Simulates Progressive Failure
Meshing, Model Trees, and visualization also bolstered
By Design News Staff -- Design News, March 6, 2005
ABAQUS Inc. has released Version 6.5 of its product suite by the same name. Among the enhancements: New capabilities in fracture and failure analysis so engineers can model damage and failure of materials, fasteners, and other connections, and predict where a crack will grow.
The fracture and failure capabilities are part of a long-term development at ABAQUS. The capabilities are in the ABAQUS/Explicit and ABAQUS/Standard products. Included in the capabilities are cohesive elements for modeling separation between two initially bonded surfaces.
"Customers such as Boeing, Exxon Mobil, Alstrom, and NASA were the driving force behind the development of our fracture and failure capabilities," says Greg Brown, ABAQUS manager of interactive products. Now, users can estimate damage and failure in fasteners, welds, adhesives, and materials, he says.
Other enhancements to ABAQUS/CAE, the company's pre- and post-processor, include: Model-Tree navigation, more robust tetrahedral meshing technology, and a "view-cut" feature. The latter allows analysts to see how analysis results vary inside a model. Says Brown, "You can actually attach yourself to any component of a model and see a movie of a simulated failure."
Also in the release, a network output database connector that allows access to ABAQUS results anywhere on a network.

| Cut Views: Analysts can employ view cuts on arbitrary surfaces and isosurfaces of a result variable, letting users examine the interior of models in ABAQUS/CAE Version 6.5. | Import: Complex geometry such as this cylinder head can be imported directly into ABAQUS/CAE Version 6.5. Then, analysts can use new geometry and meshing tools to repair and edit geometry and introduce a high-quality mesh. |
