Dilatancy in fracture of crystalline rocks
Volume changes of granite, marble, and aplite were measured during deformation in triaxial compression at confining pressure of as much as 8 kbar; stress-volumetric strain behavior is qualitatively same for these rocks and wide variety of other rocks and concrete studied elsewhere; volume changes are purely elastic at low stress; as maximum stress becomes one-third to two-thirds fracture stress at given pressure, rocks become dilatant; magnitude of dilatancy, with few exceptions, ranges from 0.2 to 2.0 times elastic volume changes that would have occurred were rock simply elastic.
