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.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
