Compatibility: Surface-Based Cohesive Behavior in UEL

Hi all,

 

I have been trying to model the surface interaction between two blocks of material using surface-based cohesive elements (*cohesive behavior). This works well in ABAQUS CAE (standard) when I set the material properties as "Mechanical, Elastic" so no problem with that.

However, I would now like to use the material properties from a fortran code. To do this, I was planning on defining the elements using *UEL with an overlay to record all the values. Is this compatible with cohesive zone elements?

The complex dynamics of people and balls bouncing on a trampoline

Submitted by manojsrinivasan on

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:

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.
