Polymer Yield Stress

Polymer Yield Stress = CONSTANT <float> []

Description / Usage

This card is required when using the Saramito yield model. The card should be included in the input when the option selected for the Polymer Constitutive Equation card is SARAMITO_OLDROYDB, SARAMITO_GIESEKUS, or SARAMITO_PTT. Definitions of the input parameters are as follows:

CONSTANT <float>

Name of the model for the yield stress. * <float> - the value of the yield stress.

This card does not have to be present for constitutive equations other than SARAMITO_OLDROYDB, SARAMITO_GIESEKUS, and SARAMITO_PTT

Examples

The following is a sample card that sets the polymer yield stress to 12:

Polymer Yield Stress = CONSTANT 12
