The Thixotropy model calculates the thixotropy from the stress in up and down stress or rate ramps. The thixotropy is defined as the area between the stress curves obtained in an up and down ramp. The thixotopy analysis uses the Area Under the Curve model to compute the thixotropic index. The normalized thixotropy is defined to compare results obtained in different stress or rate ramp ranges.
Use the Area Under the Curve model to calculate the thixotropic index in up and down stress or rate ramps.
