A bstract Stress‐strain relationships were established in a torsion machine on 6 clays with varying water content in the workable stiff‐mud range. Torsion tests gave the following measurements: (1) yield point, (2) maximum torque, (3) angle of deformation at maximum torque, and (4) angle of deformation at ultimate failure. Lawrence clay exhibited the highest angle at maximum torque and angle at ultimate failure of the plastic clays studied. Georgia kaolin had a low yield point, maximum torque, and angle at maximum torque. Workability in the stiff‐mud range is not necessarily a measure of workability of the same bodies with different moisture contents.
