We study the dynamics of the seismic activity in Mexico within a framework of dynamic scaling approach to time series fluctuations, recently suggested by Balankin (Phys. Rev. E, 76 (2007) 056120).We found that the relative seismic activity and the long-sampled fluctuations of seismic activity both display a self-affine invariance within a wide range of consecutive seismic evens.
We study the scaling properties of forced folding of thin materials of different geometry. The scaling relations implying the topological crossovers from the folding of three dimensional plates to the folding of two-dimensional sheets, and further to the packing of one-dimensional strings, are derived for elastic and plastic manifolds. These topological crossovers in the folding of plastic manifolds were observed in experiments with predominantly plastic aluminum strips of different geometry.
Hi friends,
I would like to know whether there is a particular FEA package which would incorporate 3d models from vtk on to it, say for example if abaqus incorporates it how do we do it?. Can you please help me in this regard?

HI!
I applied constant load on the viscoelastic body.
Now i want to see the displacement of one of the node with respect to time.
Can any body help me in this regard?
thank you.
Hello,
I am doing numerical simulation using ABAQUS 6.7. I faced some problem to apply load that will be used as the forced displacement in one face of our model.I used user subroutine for appling load.But, i don't know how to apply forced displacement means the command of forced displacement.
Could you please help me regarding this problem.
Regards,
Arefin
We have one postdoctoral position, available in October 2009, in the general
area of fragmentation and dynamic failure. The specific interest is in the timescales and lengthscales associated with the interactions of failure modes in materials. A background in modeling and simulation is essential, while some experience with shock physics is desirable. The successful candidate will become part of a highly collegial and diverse research group with activities in nanomaterials, planetary science and biomechanics. The work involves collaborative research with the Johns Hopkins Applied Physics Laboratory, and US citizenship is required. If you are
I have one postdoctoral position, available immediately, in the general area of mesoscale modeling. The specific interest is in the development of computationally tractable models that incorporate the appropriate lengthscales and that can be used for microstructural design. The work is in conjunction with research groups involved in the development of materials for impact applications. Examples of topics of interest include the processes of dynamic failure in specific microstructures, and the development of physics-based models that account for grain size, grain size distribution, grain rotation and texture. If you are interested, please send me (ramesh [at] jhu.edu (ramesh[at]jhu[dot]edu))

Hi all
I have a 2D model containing 2 2-D blocks rubbing on each other, producing heat at the interface. (Coupled temperature-displacement analysis in ABAQUS 6.8-1). This works fine, as the temperature on the contact surfaces in increasing.
Now, I want to get the instantaneous the heat flux per unit area due to frictional dissipation as a field output. Is there any standard subroutine or any other way to achieve that? There is no such a variable included in the standard ones.
Thanks!
Andreas
Hello everybody,
I was reading reading about R-curve behaviour of materials on the web and noticed that "crack bridging" is a considrable cause of this behaviour. but i dont have a clear understanding of this phenomenon and how it affects R-curve behaviour.
i appriciate any help.
thank you.
Hi,
I am new to ansys, does anyone know how can I create a surface to surface contact pair using batch mode. My contact elements are conta172 and targe169 (always bonded). Thank you.
