Elastic-Softening-Plasticity Around a Borehole: An Analytical and Experimental Study

Analytical solutions of near-borehole stress–strain responses are often based on simple elastic-perfectly plastic constitutive models. However, such models are incapable of capturing rock softening, and thus often disagree with observed failure patterns. Therefore, in this study, we present a set of closed-form solutions to estimate the stress–strain response around a borehole in a finite medium obeying elastic-softening-plasticity. Solutions...
