Frictional rolling contact model CONTACT version 12.1 released
Dear all,
Herewith I want to announce the release of the frictional rolling contact model CONTACT version 12.1.
The main changes with respect to earlier versions of the program are as follows:
Postdoctoral Research Associate at Brown University: Finite Element Simulations of Active Biopolymer Networks
A postdoctoral position with
primary focus on finite element simulations of active biopolymer
networks is available immediately at Shenoy Research Group @ Brown University . We are looking for a strongly
motivated candidate to work on the mechanics of active cytoskeletal
networks. The ideal candidate will have a background in solid
mechanics/computational physics with expertise in finite element simulations. Experience with Monte Carlo methods and stochastic simulations is desired but not essential. This
individual will have the opportunity to be directly involved in
UMAT Problem
Hi all,
I am
implementing the constitutive behavior of CuAlNi shape memory alloy during
uniaxial loading using UMAT. My new question is that:
When phase
transformation first starts, umat finds jacobian using my numeric finite
difference method for jacobian. But in same step, stresses and strains cannot
be obtained and then umat uses smaller and different strains and changes
jacobian values. After one step calculation abaqus job finishes with unexpected
error. What could be the problem? What can I do?
Thank you.
Call for Abstracts: Asia-Pacific Conference on Engineering Plasticity and Its Application (AEPA 2012), Singapore, 5-7 Dec. 2012
THE 11th ASIA-PACIFIC CONFERENCE ON ENGINEERING PLASTICITY AND ITS APPLICATIONS (AEPA2012)
（5 - 7 December 2012, Singapore）
We are pleased to announce that the Eleventh Asia-Pacific Conference on Engineering Plasticity and Its Applications, AEPA2012, will be held in Singapore, in December 2012, following the previous successful symposia in Hong Kong (1992), Beijing (1994), Hiroshima (1996), Seoul (1998), Hong Kong (2000), Sydney (2002), Shanghai (2004), Nagoya (2006), Daejeon (2008) and Wuhan (2010).
Title of the book required.
Dear all.
I was reading an elementary book in which it was very clearly explained about the assumeption, plane remains plane before and after bending. ( Euler - Bernouli beam theory ).
In that book author clearly explained why the plane should remain plane, what happens if it takes some other shapes like C shape or S shape.
I forgotton the books name, I request all that please let me know the title of the book.
Thanks and regards
Vinay
A website wholly devoted to buckled shells
John Hutchinson has just pointed out to me the website, shellbuckling.com. The site is devoted to the mechanics of buckled shells, with downloadable photos, slides, papers, and computer codes. The site also has a section on buckling people. The site is created by a veteran buckling person, Dr. David Bushnell, formerly of Lockheed Martin. Check the site out, and enjoy.
getting max prin stress out by python script from ABAqUS
hi all,
some how i was able to make a model by importing data in pro/e and then in abaqus.
i have a problem now that I have to take out TRESCA value and max and Min priciple stresses, for all nodes.
i was able to extract coordinates by my programm but when i substitutes "S.Tresca" for COORD in the program, it doesnt work.
Experimental study on the dielectric properties of polyacrylate dielectric elastomer
The dielectric constant of elastomeric dielectric material is an
essential physical parameter, whose value may affect the
electromechanical deformation of a dielectric elastomer actuator. Since
the dielectric constant is influenced by several external factors as
reported before, and no certain value has been confirmed to our
knowledge, in the present paper, on the basis of systematical comparison
of recent past literature, we conducted extensive works on the
measurement of dielectric properties of VHB films, involving five
influencing factors: prestretch (both equal and unequal biaxial),
electrical frequency, electrode material, stress relaxation time and
temperature. Experimental results directly show that the dielectric
