Named for Siméon Poisson, French physicist. Specifying Poisson’s ratio is equivalent to specifying the ratio of VS/VP, where VS, and VP are S- and P-wave velocities. Values ordinarily range from 0.5 (no shear strength, e.g., fluid) to 0 (but theoretically from 0.5 to –1.0; see Debski and Tarantola, 1995).[1]
