The vane shear test is a method used to determine the undrained shear strength of cohesive soils, particularly in very soft to medium conditions. The test involves inserting a vane into the soil and applying torque to measure resistance until failure occurs. Various distributions of shear strength mobilization are proposed, affecting the calculation of torque necessary for soil failure.

The vane shear test provides reliable results for determining undrained shear strength in cohesive soils.
Torque is applied to a soil-inserted vane to measure resistance and calculate shear strength.
Different shear strength mobilization distributions influence the torque required for soil failure.
A test that measures the undrained shear strength of cohesive soils by applying torque to a vane inserted into the soil.
