Hello All,
I have some questions concerning the VUMAT subroutine, I run successfully an
analysis on one element with one integration point,
so my first question is how to code for several integration points (
nblock concerns only the material points not the integration points)?
My second question is how to write for datas dependent of temperature (like Young and shear modulus)??
Thank you all for your answers.

I have been asked questions about how the shear modification was introduced to the Gurson model. I was also asked to compare my modification (see Xue L., Constitutive modeling of void shearing effect in ductile fracture of porous materials, Engineering Fracture Mechanics, 2008, 75(11):3343-3366) to John Hutchinson's modification (Nahshon, K., Hutchinson, J.W., Modification of the Gurson model for shear failure. European Journal of Mechanics A/Solids, 2008, 27:1-17).
HI,
Am trying to model prestressed box girder bridge for high speed railway analysis.Am not getting how to model prestressing force using ABAQUS/CAE.I have seen that it's not possible with CAE. Please say me an alternative way to model prestressing force.
how to plot load vs deflection graph and in multi step loading in ANSYS?
Now I am doing some work about nanotwinned copper, and don't understand what's the nature of "detwinning".
Could any disappearance of the original nanotwin structure and the formation of a single grain or a new twin structure with TBs in a different orientation and/or with different TB spacing be called detwinning?
The mechanical behavior of mono- and multi- layered graphene and carbon nanotube (CNT) systems has attracted great attention over the last decade because of their importance in nano-science and nanotechnology.
I'm new in the computer simulation of adaptive bone remodeling (Bone will adapt to the loads it is placed under). And I know many research cases of numerical model were implemented as FROTRAN subrountines for the software package ABAQUS: the bone material properties will be updated by the subroutine.
I know FROTRAN is excellent at handling large data sets for scientific coumputing and requires less resources, but I haven't learned the FROTRAN.I wonder what else irreplacable advantages of FROTRAN in the bone remodeling?

This Special Issue of the International Journal of Solids and Structures includes sixteen articles presented at the international symposium: Mechanics of Liquid and Solid Foams. The symposium was organized under the auspices of the International Union of Theoretical and Applied Mechanics (http://www.iutam.net) and was held at the University of Texas at Austin in May 8-13, 2011. The papers deal with various aspects of mechanical behavior of cellular materials and foams in particular, and represent the state of the art in the field.
