A postdoctoral research position is available at the Earth Sciences Institute, at the Hebrew University, Jerusalem, Israel, focusing on understanding basic processes of submarine landslide triggering, with applications to the Eastern Mediterranean Sea, offshore Israel. The work will involve numerical and/or physical modeling, analyzing the mechanisms of submarine slope-failure. Applicants should send their CV and intention letter including names of 3 referees, directly to the PIs: Prof.

"An alternative approach to finite plasticity based on material isomorphisms " (1999) by Prof. Bertram, the first thing that attracted my attention was the quote [by Prof. Naghdi (late)]:

 “there is some degree of disagreements on nearly all of the main constitutive ingredients and features of plasticity in the presence of finite deformation... Some of the issues of disagreements are of basic and fundamental importance.”

I am trying to model flexure of a material with softening stress-strain response. How can I model that! I know Abaqus can not handle negative tangent modulus. And, how do I simulate damage in the beam!

Any help/suggestion is highly appreciated!

Hi, everybody. I recently do some reserch on MLPG using in 3D problems, and I have modified the program in G.R. Liu's book.

But what makes me crazy is that I  must  always run the program many times to idenetifiy the proper quardrature sub-domain size to get the right result.

So I confused here, then I did a comparision of the various sub-domain size to examinate the effect of them in G.R. Liu's MLPG2D program. This time, sub-domain size seems have liittle effect on the result. I tried 0.1*nodalspace situation, and results has a about 20% error.
