Hysteresis loop

Hi,

Does anybody know how to plot the stress-strain (check the strain rate effect) and hysteresis loops by using Abaqus?

 Regards,

 

Abaqus Low cycle fatigue - Hysteresis Energy Criteria

Hi,

I am trying to do Low cycle fatigue analysis in abaqus, and
according to the Documentation, for bulk material damage initiation and damage
evolution definition, I can use the criteria (and type for Damage evolution) as
"Hysteresis Energy". And have to define 4 material variables C1 to
C4.

But in the abaqus material library (in abaqus-CAE) i could find
all the other criteria but not the "Hysteresis energy". I also tried
to define it in the *.inp file but abaqus could not read it (apparently wasn't
writing it correctly).

Electromechanical hysteresis and coexistent states in dielectric elastomers

Active polymers are being developed to mimic a salient feature of life: movement in response to stimuli. Large deformation can lead to intriguing phenomena; for example, recent experiments have shown that a voltage can deform a layer of a dielectric elastomer into two coexistent states, one being flat and the other wrinkled. This observation, as well as the needs to analyze large deformation under diverse stimuli, has led us to reexamine the theory of electromechanics.
