【 摘 要 】

The authors have found experimentally that elastic wave velocity depends on compressive stresses in tubular samples made of equivalent geomaterials. The relation between the wave velocity and tangent modulus of elasticity is determined. The values of the dynamic modulus of elasticity as function of the compressive stress are obtained.
