Over-torque protections to prevent system damage
Description
The laboratory vane shear test method is used to determine quick estimates of the undrained shear strength of very soft to stiff saturated fine-grained clayey soils. The test involves inserting a four-bladed vane into an intact sample (i.e. Shelby tube) or remolded sample and rotating it to determine the torque required to cause shearing. The measured torque is then converted to shearing resistance. The method can also be considered for investigating strength anisotropy in vertical and horizontal directions.
