Dear colleagues,
I would like to bring to your attention the advanced course on Modeling of localized inelastic deformation that will be taught by Milan Jirasek in Prague, Czech Republic on 13-17 September 2010.
More detailed information on the course is posted at http://mech.fsv.cvut.cz/~milan/course2010.html. We are looking forward to seeing you in Prague!
Hey.
I want to model an anchored sheet pile wall placed in a completly saturated clay material, where
the excavation steps on the left side of the wall have to be taken into account.
I am using the keyword in ABAQUS "*Model change, Remove" to remove my elements, so I can
simulate the excavation steps. Unfortunately, my pore pressures seem stranges in the
model when I am using this keyword.
The University of New Mexico, Department of Mathematics and Statistics, and/or the Department of Mechanical Engineering, is seeking candidates for a post-doctoral position to conduct research in the area of computational geomechanics for a project related to modeling the effect of rock joints on tunnel failure. A start date about June 1, 2010 is anticipated, subject to final budgetary approval. A Ph.D.
Dear Colleague: Please consider submitting your nanomechanics related abstract to Symposium 4-1 ("Nanomechanics: Beyond Modulus and Hardness") of the 47th Annual Technical Meeting of Society of Engineering Science, which takes place October 4-6, 2010 at Iowa State University, Ames, IA. The deadline for abstract submission is 5:00pm CST, Monday, June 7, 2010. The meeting's homepage can be found at www.ucs.iastate.edu/mnet/ses2010/home.html.
Applicants are invited for an immediate opening of a postdoctoral
researcher position at Northwestern University. This researcher will work on
a research project on vibration energy harvesting that involves close
collaborations with experimentalist. Candidates should possess an earned
Ph.D. in Mechanical Engineering, Physical sciences, Electrical Engineering,
Material Science, or related disciplines. Candidate should have a strong
theoretical background in solid mechanics and previous experience in solving

Engineering groups have traditionally relied on linear, finite element analysis
Dielectric elastomer can undergo giant deformation, but are susceptive to various failure modes. i.e electrical breakdown.
Some experimental papers (Kofod, Plante, Chen, see the attachment) reported the dielectric strength of VHB material (a kind of dielectric elastomer) under difference pre-stretch, equal bi-axially or unequal bi-axially. And the strength (maximum voltage can be applied before breakdown) has be greatly improved by these mechanical stretches.
So here comes the question: is the dielectric strength dependent or independent of stretch？
