The The Preliminary Program is now ready here on the website
You can still registrer for the conference.
We send out invitations directly to those of you who have registrered so that you can join our LinkedIn Group. Here you can post a discussion, find new connections and start getting ready for the ICCM20. Hope to see you in Copenhagen soon!
The Computational Mechanics group at The University of Iowa, led by Professor S. Rahman, is looking for new Ph.D. students, who are capable of and interested in performing high-quality research on engineering design. The research, supported by National Science Foundation and others, entails building a solid mathematical foundation, devising efficient numerical algorithms, and developing practical computational tools for stochastic design optimization. A substantial background in solid mechanics and structural optimization is a must; exposures to stochastics and probabilistic methods are highly desirable.
If you are interested in pursuing a Ph.D. degree at Iowa, please contact and send a resume to: Professor Sharif Rahman at sharif-rahman [at] uiowa.edu. Please note that we are interested in students who already have M.S. degrees in engineering or mathematics. The desired start date is Spring 2016 or sooner.

Abstract of the article is below:
Development of advanced materials for high-end applications is driven by the increasing understanding of the dynamics and properties of defect microstructures, leading to the ability to synthesize and control materials microstructures to meet specific application demands. Dislocation motion is the fundamental physical mechanism of the plastic deformation process in crystalline materials.
Call for Papers
Hi my Friends,
I am doing abaqus run for a copper specimen under hydrostatic pressure. The magnetude of pressure is in order of several Giga Pascals. In my material definition, I have defined stress-strain flow up to strain of 0.4. But as you can see in attached photo, some elements show very large deformation (considerably larger than 0.4). Knowing that I have not defined stress strain behaviour for srain greater than 0.4, how this can be occure? Unfortunately, niether adaptive meshing nor element deletation were not eliminate this issue!!
Best Thanks
