ABAQUS Keywords Reference Manual  

*HYSTERESIS
Specify a rate-dependent elastomer model.

This option is used to specify the creep part of the material model for the hysteretic behavior of elastomers.

Product: ABAQUS/Standard  

Type: Model data

Level: Model  

Reference:
There are no parameters associated with this option.

Data line to define the creep behavior: 

First (and only) line:

  1. Stress scaling factor, S.

  2. Creep parameter, A.

  3. Effective stress exponent, m.

  4. Creep strain exponent, .

  5. Constant, , for regularizing the creep strain rate near the undeformed state. The value of should be non-negative. If this field is left blank, the default value of 0.01 is used.

Typical values of these parameters for common elastomers are given in “Hysteresis in elastomers,” Section 17.8.1 of the ABAQUS Analysis User's Manual.
