Title: Elastic Coefficients of Porous Rocks as Function of Previous HitEffectiveNext Hit Stresses: ABSTRACT

Author(s): V. S. Tuman

Article Type: Meeting abstract


An elastic energy pulse is generated in a pressure chamber (triaxial system) containing a cylindrical rock sample. The dynamic elastic coefficients of the porous rock are determined by analyzing the first arrivals and the later events of elastic energy. The pulse durations are less than one microsecond. By changing the Previous HiteffectiveNext Hit pressures in the triaxial system the elastic coefficients of the rock sample are varied. The variation of the elastic coefficients have been measured as a function of Previous HiteffectiveTop stresses.
