Abstract

A plane-strain apparatus for "soft" (unconfined compressive strengths below 35 MPa) rock has been designed and built at the University of Minnesota based upon a passive, stiff-frame design. The unique feature of the device is that no kinematic constraints are imposed on the formation of a shear band. By placing the upper platen on a linear bearing, the specimen has the freedom to form a failure mechanism consisting of two elastic bodies separated by a localized zone of deformation. Thus, the apparatus has the advantages of both direct shear and conventional compression testing.
