This basic question is discussed in a paper with S. Osovski and A. Venkert, to appear in Mechanics of Materials.

We definitely enjoyed working on this aspect of the dynamic shear localization failure process (aka adiabatic shear) and I hope you will enjoy reading it! Comments are welcome :=)
Here we are to answer any qustion of finite element modeling in abaqus and ansys.
do u have any question?
we do it for you...
hi all,
i was able to model a concrete beam in ansys
but i am having problem with applying laod ( using load steps ......and restsrt)
and reading results (when to know the that the beam failed and how to know what kind of fail happpend)
and how to use ( arc length instead of newton-rafson)
please can you suggest any pdf which i can learn from or any on has an example for a beam ( as text file so i can learn the commands)
thanks
It is my pleasure to announce the launch of the "Eshelby-UH Mechanics Award for Young Faculty". This award will be given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.
The NNIN/C at the University of Michigan will be hosting a presentation on ”System Level Analysis & Simulation for MEMS”, which will be broadcast live as a web based seminar.
The Webinar will be webcast live from 1:00 PM - 2:00 PM EDT on 31st October, 2012.
New Technologies - Research Centre at the University of West Bohemia
(Czech Republic) invites applications for a postdoctoral position in the
field of FE software development. Highly motivated individuals holding a
PhD in applied mathematics or mechanics, numerical analysis and
programming or closely related fields are encouraged to apply.
The postdoc position in the field of FE software development is focused
on mathematical description of contact algorithms for deformable bodies

Hi all,
I am looking for an algorithm to get the inverse of a 4th rank tensor (e.g. the compliance tensor S_(ijkl) from elastic stiffness tensor C_(ijkl)) S_(ijkl)=C_(ijkl)^(-1)
I am programming in FORTRAN, and for this purpose I wasn't able to find neither any algorithm nor any existing subroutine.
If anyone at this forum has any idea about this inversion, kindly guide me.
Best regards,
Mubeen.
I want to start a dynamic calculation in Abaqus in which, for every node, I specify the displacements, velocities and accelerations. I know that by the *IMPORT command, I can start a calculation with a deformed mesh, and that the velocities can be defined by in the *INITIAL CONDITIONS, but how to deal with non zero user defined accelerations? Have any body did that? Is it possible with a subroutine?
Thanks for any help
