*HYPOELASTIC
Specify hypoelastic material properties.

This option is used to define a nonlinear, small-strain elastic material.

Products: Abaqus/Standard  Abaqus/CAE  

Type: Model data

Level: Model  

Abaqus/CAE: Property module

Optional parameter:

USER

Include this parameter if the moduli are defined in user subroutine UHYPEL. Omit this parameter if the moduli are defined on the data lines.

Data lines to define hypoelasticity by specifying the material constants directly: 

First line:

  1. Instantaneous Young's modulus, E.

  2. Instantaneous Poisson's ratio, .

  3. First strain invariant, .

  4. Second strain invariant, .

  5. Third strain invariant, .

Repeat this data line as often as necessary to define the variation of the moduli with the strain invariants.

To define hypoelasticity by a user subroutine: 

No data lines are used with this option when the USER parameter is specified. Instead, user subroutine UHYPEL must be used to define the hypoelasticity.
