Fig. 9

Schematic of the cone and plate geometry for shear rheometry. The blue portion is the sample, the purple arm is the base plate, and the orange portion is the top plate, which is either a flat plate or a cone. The angle \(\theta\) indicates the angle of the cone, which is typically between 0.25 and \(4^{\circ }\). The arrows indicate the direction of force applied to the sample.
