We obtain a numerical-analytic solution of an antiplane problem of the stress-strain state of elastoplastic half space containing a periodic system of thin rigid tunnel inclusions parallel to the boundary of the half space. Prior to loading, these inclusions were in unilateral mechanical contact with the medium. We determine the stress-strain state and study the phenomenon of plastic exfoliation of the inclusions. The diagrams of the critical load are plotted on the coordinates of the geometric parameters of the system of inclusions under the condition of constancy of the critical length of interface plastic strips.
