Join our Shells and Continuum Shells webinar

Posted by Laurence Marks

This months webinar is a repeat of one presented in February 2014. In this back to basics lecture we will look at the traditional shell elements in Abaqus and their definition, then run through what a continuum shell is, how it is defined and what it offers.

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.
