ABAQUS error
Hello everyone,
I am modelling a three dimensional cohesive element problem with Abaqus. I was wondering to see if anyone had the following error in their analysis:

3D FEA of stress concentration
Dear all,
I am simulating tensile specimens with an elliptical pore(representing a flaw in the material) in the mid-cross section of the specimen. What I am looking for is the stress concentration caused by this pore.
I am simulating this as a 3D specimen under tensile loading only, with 3D, 8-node linear brick elements(1st order). Now my questions are:
1- Is there any analytical solution for such problems(3D with elliptical pore) with which I can compare my FEA results?
Two PhD positions available at the Department of Petroleum Engineering, Texas A&M University
<p>Two PhD positions are available at the Department of Petroleum Engineering, Texas A&M University in the area of characterization and micromechanical modeling of organic-rich shales. Candidates should have a BS or MS degree in civil engineering, mechanical engineering, petroleum engineering, material science or other related areas. Candidates with background in experimental and modeling of porous materials are highly preferred.
Characteristic impedance of a tube
Hi all,
I need to calculate the characteristic (or specific) impedance of a tube. Generally this tube has a varing cross-sectional area (diameter changes and it has tube is not cylidrical). However for a very simplified case, let's assume it is a perfect cylender terminated at a finite length. The walls and termination are not rigid so it will have interaction with acoustic pressure inside.

A single theory for some quasi-static, supersonic, atomic, and tectonic scale applications of dislocations
Xiaohan Zhang Amit Acharya Noel J. Walkington Jacobo Bielak
We describe a model based in continuum mechanics that reduces the study of a significant class of problems of discrete dislocation dynamics to questions of the modern theory of continuum plasticity. As applications, we explore the questions of the existence of a Peierls stress in a continuum theory, dislocation annihilation, dislocation dissociation, finite-speed-of-propagation effects of elastic waves vis-a-vis dynamic dislocation fields, supersonic dislocation motion, and short-slip duration in rupture dynamics.
