Notizen:
A closed-form analysis for elastic - plastic response of a circular hole in an infinite Mohr - Coulomb medium under axisymmetric loading shows the effect of repeated loading on the stress and displacement fields around the hole. Examples show how repeat-load closure increment is affected by working load, internal pressure, material compressive strength and internal friction. The solution is used to predict results of a laboratory test performed on a rock simulant specimen that contained a reinforced hole. Analytical and laboratory results are similar: at small closures (a few per cent, but well into the plastic response range), the closure increment from an unload - reload cycle is small compared with the initial closure. Closure increments for each of several cycles are comparable and cumulative.
