Hi, friends,
Now, I am implementing the non-local continuum theory in ABAQUS through UMAT programming.
Unfortunately, I have been obstacled by the following question:
On one hand, in non-local continuum theory, the non-local strain of every particular integration point is determined by the global strain field all over the specimen.
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

Hi,
I have modeled a two phase unit cell with one inclusion in a soft matrix. I have applied appropriate periodic boundary conditions. Load is applied a displacement. I have solved the problem using FEA through ABAQUS. Now I want macroscopic stress-strain response of the material.
What I have done is, taken the Reaction force and divided it by the area and similary displacement and didvided by length, will this give me the stress-strain response or do I have to use some homogenisation methods.
Thank You
Regards
Ghouse
Hi,
I am not able to work out he motion of the screw in Finite Element Method. I am using MSC software. Please help.

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.
