It’s better to travel hopefully..

Posted by Laurence Marks

“So gentlemen, I give you the Mark 74, and that is as far as these things will ever, and can ever, be developed.” It’s not something you often hear is it? Product development is an ongoing, almost never ending process; a journey rather than a one off event. Unless you were the British Motorcycle industry in the 1960’s and 70’s.

Anisotropy In Canmaking - Crown Technology

Posted by Robert Done - Crown Technology

There are two main applications for FEA in canmaking; predicting the performance of a product and evaluating forming processes. In each case, anisotropic material models can enhance the simulations’ accuracy. For example, typical performance requirements for a beverage can include the reversal pressure of the dome and the resistance of the dome in a drop test. Typically, a can will fail under both of these test conditions by buckling of the dome. As we know, the predicted buckling load of a perfect dome under symmetric loading will usually be significantly higher than in any practical case since a perfect dome does not exist. Anisotropy in the material model is a good way of introducing physically realistic asymmetry into the model and obtaining a plausible buckling result.

John Drapers last DS talk.. Understanding fe-safe and the bridge between Research and Design

Posted by Laurence Marks

For some while I’ve been meaning to write about Professor John Draper’s last lecture as a Dassault employee. Given that it was in June last year I’d better get on with it.

Join our Coupled Analysis Webinar

Posted by Stephanie

February’s webinar will cover an introduction to sequentially coupled analyses. It will be held on Friday 24th February.

This webinar will present various methods for transferring results between Abaqus analyses or between Abaqus and a third-party software. These methods are particularly useful to perform sequentially coupled multi-physics simulations such as thermal-structural analysis or fluid structure interaction. They can also be applied when an analysis requires the use of both solvers: Abaqus/Standard and Abaqus/Explicit, such as the analysis of the residual strength after impact.

Merry Christmas - Virtual Bell Simulation!

Posted by Graeme Short

Merry Christmas everyone. If you are reading this, I assume you haven’t just stumbled across it, and have been lead here either from an SSA email or some form of content feed. If that’s the case, I’m sure you’ve also seen the SSA Christmas newsletter which includes the traditional SSA festive message set against the backdrop of some virtual bells chiming.

Element deletion with general contact: Contact tutorial 7

Posted by Matt Toon

As I have stated before contact is everywhere. (And I still wonder why the real world finds it simple to handle, whereas in the simulation domain its always a bit tricky.) But this time I want to move on from simple contact, if such a thing exists, to the sort of contact which occurs when a projectile penetrates a target.
