Abstract
The effects of stress state and stress ratio on the maximum shear modulus, obtained from in-situ downhole and crosshole shear wave velocity tests were evaluated in the model tests. The hydraulic gradient similitude method was used to increase and control the model stress level. The downhole and crosshole shear waves were generated and received along the principal stress axes using piezoceramic bender elements. It was found that (1) the shear wave velocity is dependent upon the individual principal stresses in the directions of wave propagation and particle motion, and (2) only the stress ratio defined in the plane of wave propagation has some effects on the shear wave velocity.
