How to postprocess the stress fields if UEL (abaqus) is used

Submitted by Wugui Jiang on

Dear everybody,

  I had embeded the ferroelectric constitutive law into ABAQUS via UEL.  The stresses of ferroelectric devices in service are predicted, but it is too difficult to postprocess.

   Would you like tell me how to output in detail if you knew.

Seeking for a PhD or Research position in APPLIED MECHANICS

Submitted by nunziovitt on

Hi, guys...

I am a 26 years old Mechanical Engineer (newly graduated).

Can somebody tell me where I can find a very good PhD studentship in APPLIED MECHANICS (i.e. vibro-acoustics, control systems, vehicle dynamics, etc...) in Europe? Or something like a Research fellow (1 or 2 years would be great)?

 I'm getting crazy with that... I hope somebody can help me.

Mechanics associated with grain-boundary diffusion and sliding in polycrystals and its application to nanocrystals

Submitted by Yujie Wei on

As stated by Richard Vinci and Oliver Kraft in the announcement of 2008 Gordon Research Conference on Thin Film and Small-Scale Mechanical Behavior, there is a compelling need to understand the critical roles of different deformation mechanisms in structures with small characteristic dimensions, like nanocrystals and thin films. We have recently studied deformation behaviors in nanostructured materials and thin films with deformation mechanisms including grain-boundary diffusion, grain-boundary sliding, and grain-interior plasticity. Some interesting mechanical phenomena associated with heterogeneous grain-boundary properties are found and summarized here.
