The complex dynamics of people and balls bouncing on a trampoline
Here is a webpage with a number of videos, both experiments and matlab animations, of balls and people bouncing on a trampoline. Also, links to a paper in PLOS ONE.

The interesting phenomenon is that when two balls are in simultaneous contact with each other, there is a dramatic energy transfer from one ball to the other.
Here is an article in Popular Science about the phenomenon:
Mesher for Spectral Element Method
Hi,
Is there a free/open-source mesher for the Spectral Element Method?
I know some researchers use a conventional mesher with order 3 elements
and then include more nodes in the meshes (but without improve the
geometric interpolation).
Thanks in advance,
Two Post-doctoral Associate Positions Available at Rice University
Position Description: Two postdoctoral associate positions, one in computations and one in experiments, are available at Rice University. The first position is in the area of atomistic and molecular modeling of nanoscale defects, dislocations and mechanics of complex, low symmetry compounds. The computational techniques will be integrated to approaches from statistical mechanics and physical chemistry to provide quantitative predictions of properties of complex materials across different time- and length-scales.
p-delta in ansys
2 question
1) how can i do p-delta analysis in ansys ?
2) how can i determain dynamic responses ( frequencies and mode shape ) from results of p-delta above in ansys?
CSC Positions at Cardiff University in Computational Mechanics - CSC in Computational Mechanics
Cardiff School of Engineering invites applications for support for China Scholarship Council award holders. The awards will cover tuition fees at the overseas rate for 3 years for applicants who secure a China Scholarship Council award to cover living costs.
Stresses interpretation in ABAQUS
Hi,
I am doing the beam tutorial in ABAQUS and I get the mises stress output as given in the tutorial document (ABAQUS manual appendix B).
I am trying to understand the S11, S22 and S33 outputs from this model. The document I am using for my steps are attached. Couldn't attach my .cae file here.
Surgical Simulation Post-Doc available
One post-doctoral fellowship is available in RealTcut, funded by the Strasbourg Institute of Advanced Study
http://www.usias.fr/fr/fellows-2013/
The goal of the post-doc is to extend the preliminary results which can be seen here: http://youtu.be/KqM7rh6sE8s and will appear shortly in the journal Medical Image Analysis
Difference between different material models for Hyperelastic material
Hello,
I am doing a project on rubber couplings and it is a bit difficult for me to decide between the material models availavle in Ansys 14. I am new to this field and want some assistance in choosing the material model. So, can anyone help me to theoroticall explain the difference between the different material models available in Ansys?
