5th MPM Workshop

Thursday and Friday, April 2-3, 2009
Oregon State University Corvallis, OR, 97331


This one and half day workshop featured presentations on theory and application of the material point method (MPM) as a numerical method for solving problems in solid mechanics, composites, fracture, problems involving interfaces and contact, multi-scale and multi-physics problems, and more. The workshop included some time for discussion about MPM as well. The conference was made possible by support from Sandia National Lab.

A 6th MPM Workshop is anticipated to be held around the same time in 2010. If you would like to be added to the future mailing list, send yours email address to John Nairn and it will be forward to next year's organizer.
