Viscoelasticity in Abaqus

Submitted by Andreas Burger on

Hi All,

 I would like to use Abaqus to model the viscoelastic material  behaviour of a polymer.



I have material data from a simple uniaxial creep experiment (nominal strain vs time).  I tried to use the viscoelastic material model in Abaqus.  I am a bit confused as to how I need to enter my data (what format). 

The manual says I have to specify the normalized bulk and normalized shear compliance . 

  


where is the shear compliance and the volumetric compliance

Puzzle: What caused this failure?

Submitted by Biswajit Banerjee on

Here's a puzzle for our readers.  The following image is of the surface of a failed joint followed by a picture of the joint (not the same one but a similar one) before joining.  What material is it? What caused the failure?  All manner of speculation is welcome.

We need a travelling long distance microscope for measurement of crack length

Submitted by kaslantas on

Hi

I am looking for a travelling long distance microscope for measurement of crack length. I will use this microscope on Instron fatigue test machine. I found some long distance microscopes on the web. But they are not appropriate for us. I attached a figure showing the travelling microscope that I would like to buy.

Do you have any suggestion about it? Where can I find it?

Thanks 

ANSYS Simulation

Submitted by shneerow on

Dear All,

 Is there a source of free material data property files for use in ANSYS Simulation? I am looking for a file representing the properties of Neodymium Iron Boron (38) (permanent magnet material) to apply to a simulation of a motor. 

 Thanks for any help!
