************ Yield Stress ************ :: Yield Stress = CONSTANT [M/Lt2] ----------------------- **Description / Usage** ----------------------- This card is used to specify the model for the yield stress parameter, :math:`τ_y`, of the **BINGHAM** and **HERSCHEL_BULKLEY** model options of the *Liquid Constitutive Equation* card. Definitions of the input parameters are as follows: +-----------------+------------------------------------------------------------------------------------------------------------+ |**CONSTANT** |Name of the model for the yield stress. | | | | | | * - the value of the yield stress, τy, which has the dimensions of stress, in whatever units are | | | consistent with the problem and marks the transition from solid-like to fluid-like behavior for the | | | Bingham-Carreau-Yasuda model. | +-----------------+------------------------------------------------------------------------------------------------------------+ ------------ **Examples** ------------ The following is a sample card that sets the yield stress to 100: :: Yield Stress = CONSTANT 100. ------------------------- **Technical Discussion** ------------------------- See Description/Usage for *Liquid Constitutive Equation* card.
