I am having problems in writing the umat and uexpan subroutines applicable to the creep model defined in

Has anybody written the algorithm?
One PhD student position is available at Arizona State University for fall 2014. Research background in at least one of the following areas is preferred.
1. Fatigue, creep, and corrosion analysis of materials
2. Computational mechanics and micromechanics
3. Damage detection for composite materials
Interested candidates please send application documents to yongming.liu [at] asu.edu (yongming[dot]liu[at]asu[dot]edu)
In 2012 and 2013 we organized very successful Workshops on
"Physics-based material models and experimental observations" funded
by the European Union's Enlargement programme. We cordially invite you to
submit an abstract to the 3rd International Workshop on Physics Based
Material Models and Experimental Observations to be held on 2-4 June
2014 in Cesme-Izmir/Turkey.
In this paper, the mechanical behavior of freestanding thin sputter-deposited films of Au is studied at temperatures up to 340°C using tensile testing. Films tested at elevated temperatures exhibit a significant decrease in flow stress and stiffness. Furthermore the flow stress decreases with decreasing film thickness, contravening the usual notion that “smaller is stronger”. This behavior is attributed mainly to diffusion-facilitated grain boundary sliding.
This paper has been accepted by Scripta Materialia.
I am
carrying out a non-linear analysis of a concrete section subjected to construction
loading. I am looking to model the time-dependent effects of the material
properties as well as creep and shrinkage properties of concrete. In the ABAQUS
manual it states the General Static procedure
cannot be used to model time dependent effects. Naturally the Riks Method would be ideal to account of
the non-linear effects however it doesn’t allow for the use of multiple steps in
the analysis which is necessary to model the various stages of construction
