Hi all,

I am using FEAP 8.2 in my university, and have to write a user material routine, but there is no clear guideline/example about which files to modify for this purpose. Sorry to say, the programmer's manual is very short, and very little detail is there.

The old tutorials/examples based on FEAP (7.x) are no longer helpful because the FEAP 8.2, 8.3 source code has changed considerably (atlease the files in user folder), hence the novice can get mad after trying for many weeks to figure out the way for doing this.

Dear all,

please find information about the 5 day - course on Plasticity and Microstructures at CISM Udine, Italy.

The link is:

Flyer is attached.

Best regards,

Mubeen

Plasticity and Beyond: Microstructures, Crystal-Plasticity and Phase Transitions

June 27, 2011 — July 1, 2011

Coordinators:

I read this article today, perhaps other beginners like me can also get some benefit from this:

I am confused about the use of two-point tensors in elasticity. The deformation tensor F and first PK tensor are two point tensors, and the "two-point" property arises from use of two different Coordinate System When a continuum body is deformed, why it is necessary to move the Coordinate System as well? (or alternatively, why the coordinate system is attached to the body itself??, isn't it possible to use a general coordinate system which can represent the deformations and also account for the rigid body rotations of the continuum body?).

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.

I am looking for introductory-level papers/texts on multiscale modelling of solids. Please suggest some titles which give introduction alongwith a summary about the latest advances in this field. I will be thankful for your suggestions.
