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


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

Polymer Yield Stress = CONSTANT 12
