Uniaxial and Triaxial Creep and Failure Tests on Rock: Experimental Technique and Interpretation

  • U. Hunsche
Part of the International Centre for Mechanical Sciences book series (CISM, volume 350)

Abstract

Modern test equipment and experimental techniques for uniaxial and triaxial failure tests, deformation tests, and creep tests are shown with special emphasis on tests on soft rocks and on time effects. A large number of test results, mainly on rock salt, and their interpretation is given. Besides uniaxial and triaxial creep tests on cylinders, true triaxial tests on cubes and tension tests are also included. Determinaton of elastic constants, performance of stress drop and relaxation tests are presented as well. Emphasis is placed on the identification of the physical mechanisms for creep and fracture and on the determination of volume change.
