How to deal with the constitutive integration in plasticity?

Submitted by Bin Ji on

Plastic theory has been developed systematically. As a beginner, however, some questions have confused me for a long time.

As is well known, the constitutive integration must be deal with in the flow theory. Instead of the explicit algorithm such as M-iteration, the implicit one - stress update algorithm - has been attractive for its simplicity, the most famous of which is rp (return mapping) for J2 flow theory.

Graduate Student or Graduate Employee?

Submitted by Amit.Ranade on

Lately I have been thinking that "Graduate Student" is a misnomer. The correct title should be "Graduate Research Assistant" or "Graduate Engineer".  After more than a year spent in industry, I think that there really is no difference in the work done. Except that the work environment is more flexible in academia.

Kindle - The Future of Ink, part 2

Submitted by Michael H. Suo on

A year ago in my first post, The Future of Ink, I explored e-ink technology and the e-book concept when the potential was still largely unseen. But since then, the industry has completely transformed, and the prospect of the e-book is beginning to be realized.
