When reading papers about visco-plastic or elasto-viscoplastic simulation, all authors only say that the orientation of grain used in the simulation can be randomly generated, and does not refer to how to generate them. I know the orientation of grain can be expressed by Euler angles (phi1, ph, phi2), but can someone give me advice how to generate euler angles?

Dear All,

How do find the inverse of the rectangular matrix.

The Department of Mechanical Engineering at the University of Colorado
at Boulder invites applications for two full-time positions beginning
fall 2010. The positions are for tenure-track assistant professors with
disciplinary expertise in the areas of (1) Bioengineering (posting #808181), and (2) Solid Mechanics/Materials Physics (posting #808182);
higher rank may be considered for experienced candidates. Candidates
are expected to strongly complement and strengthen existing
departmental research in biomechanical/biomaterials engineering, energy
and environmental engineering, micro/nanosystems engineering, materials
engineering or solid/fluid mechanics. Candidates must have an earned

This workshop is being organized under the auspices of the International Federation for the Promotion of Mechanism and Machine Science (IFToMM).

Topics of interest include: Microactuators, Microsensors, Micro-opto-mechanical devices, Mechanical Tools for cell and tissue studies, Micromanipulation, Micro-assembly, Microscale flight and swimming, Surgical tools, Micro-robotics, Micro-scale power generation, and Miniature manufacturing machines.

Please consult the Call for Papers (attached) for further details.

The Department of Mechanical Engineering seeks an outstanding individual for a tenure-track faculty position in Mechanics.  The appointment is expected to be at the assistant professor level; in an exceptional case, a senior faculty appointment may be possible. Faculty duties include teaching at the undergraduate and graduate levels, development of an independent, internationally-recognized research program, and supervision of student research.

The Department of Mechanical and Industrial Engineering at Northeastern University invites applications and nominations for a tenured faculty position beginning in September 2010 at the Associate or Full Professor level. Candidates with well established, well funded and internationally recognized research programs are sought to expand the department’s research efforts. The position is in the general area of Nanotechnology, preferably with an emphasis in mechanics. Collaboration with our NSF funded Center for High-rate Nanomanufacturing as well as excellence in teaching are expected.

We present an application of fluid-structure interaction analysis to the mechanics of red blood cells. For more information see the following link:

I am interested in the computational crystal plasticity (elastic-viscoplastic models), and I intend to start working in this area. Therefore, I am looking for some review papers--

1- which provide an overview of the state-of-art in this area (a summary of the recognised single crystal plasticity models).

2- about the application of single crystal plasticity using micromechanics based  multiscale FEM for the prediction of texture evolution.

I will be very thankful if sombody can answer these queries.

Hi all...

I am new to abaqus. I have to model cone penetration test (CPT) in abaqus.

I am using drucker prager plasticity and hardening to model the soil.

The cohesion (d) decreases as plastic strain increases. But how do i input this into the model ?

Drucker prager hardening inputs have yield stress and plastic strain columns.

So from cohesion, how do i get the yield stress values ?
