hi ,
How to vary strain rate in abaqus explicit in tensile test simulation.
i know the expression in tensile test that strain rate = velocity / gauge length, but how can m decide the step time.
for example ifthe strain rate is 100 sec-1, and gauge length is 25 mm thn the velocity is 1.66*e-5 m/s. so what is the step time in this case................
any body tell me the relation between strain rate and step time.
thanks in advance
Dear Colleagues:
Please, consider to attend the symposium entitled "Behavior and Mechanics of Active Materials & Structures" organized for the occasion of the 52nd Annual Technical Meeting of the Society of Engineering Science (SES). The SES meeting will be held at Texas A&M University, October 26 - 28, 2015 (http://ses-2015.org/).
Graduate Distance Education Course for Fall 2015 at Iowa State University
EM/ME 566X Phase Transformations in Elastic Materials
Instructor: Valery I. Levitas

I'll be teaching an undergraduate course on engineering thermodynamics. We will use the textbook by Cengel and Boles. I will supplement the textbook using my own notes on thermodynamics. Teaching this course will give me an opportunity to revise these notes and add new pieces. Here are notes for the opening lecture.
Postdoctoral Fellow Positions: Interdisciplinary Projects between University of Notre Dame, University of Pennsylvania and Argonne National Laboratory
A new postdoctoral fellow position will start on 1 November 2015 at the Technion – Israel Institute of Technology. The position is in the area of theoretical and computational modeling of dynamic failure in soft solids. The potential candidate should have a Ph.D.
The Department of Mechanical Engineering at Stanford University (http://me.stanford.edu/) invites applications for a tenure-track faculty appointment at the junior level (Assistant or untenured Associate Professor). Applications will be reviewed across all disciplines of mechanical engineering. As part of recent strategic planning, the department has identified special hiring needs and opportunities in controls, robotics, manufacturing, and biomedical engineering.
MIT invites top early career women in Civil and Environmental Engineering (CEE) and related domains (e.g. mechanics, materials, environmental and earth science) who are interested in careers in academia to apply to attend this new innovative workshop to be held on the MIT campus.
Pre-conference workshop at TERMIS 2015: Past, Present Future: The Evolution of Regenerative Medicine
Hi all,
I have a 20 node hexahedral "Thermomechanical" element in our inhouse software which i am trying to validate against Abaqus .
The problem is, the displacements, nodal forces match exactly ( Just compared the max min values in the legends! and checked a few random nodes).
The Abaqus input file is attached:
The problem is as follows:
One single element is chosen with a linear elastic material model (Some parameters are chosen in an unphysical manner but here the idea is
to just validate the implementation):
