Input file for the CPFE VUMAT in Nonlinear finite elements for continua and structure

Submitted by rctron on

I am learning crystal plasticity and its implementation as VUMAT subroutine from the book Nonlinear finite elements for continua and structure. I am aiming to gain more insight about the implementation by studying the poly-slip, rate-dependent, single crystal plasticity subroutine provided in the solution manual.

However, I couldn't reproduce the example in the book successfully, as I believe I have made errors in defining the material properties in the Abaqus input file. So, can someone please provide the input file for the associated VUMAT subroutine?

Book Review

Submitted by Pradeep Sharma on

Micromechanics---loosely speaking, is the study of heterogeneities in materials and its consequences for material or continuum behavior. This encompasses studies of inclusions, dislocations, cracks or more generally defects. A related problem is that of "coarse-graining" or in other words the effective homogenized properties of a heterogeneous material. The latter is a recurring theme in all of physical sciences not just solid mechanics. Micromechanics, a formidable subject by all means, dominated a substantial part of the history of solid mechanics. Several of our Timoshenko awardees have been associated with this subject, e.g. Eshelby, Hill, Keller, Irwin, Rice among others.
