Hollow cylinder torsional shear test is simulated regarded as a boundary value problem employing a three-dimensional static/dynamic soil-water coupled finite deformation analysis to investigate the influence of the specimen geometries on apparent behavior concerned in practical experiments. 1) A “Perfect path” which means the response of a single three-dimensional element with uniform deformation is calculated to investigate the effect of non-uniformities on the apparent behavior. As can be seen, only the apparent behavior with thinnest wall thickness coincides with the “Perfect path”, which indicates a uniform deformation inside the thinnest specimen; 2) It was found that when the cylinder wall thickness became smaller, the non-uniformity also decreased correspondingly, which can also be seen in the element behaviors of the thickest specimen; 3) Even thought the non-uniformity in different geometries is quite different, there seem to be no significant influence on the apparent behavior. The reason may lie in the extreme constraint conditions, namely displacement control.
