Experimental Study of the Mechanical Characteristics of a Rock-Like Material Containing a Preexisting Fissure under Loading and Unloading Triaxial Compression

<div>Relationships between the unloading ratios of the confining pressure and the variations of the deformation modulus. (a) Unloading ratios of the confining pressure vs variations of the axial deformation modulus. (b) Unloading ratios of the confining pressure vs variations of the circumferential deformation modulus.</div>
