Abstract

A partial closure of a variable -width crack in a non-uniform stressed field is mathematically described. The occurrence of several crack face contact areas is investigated. It is assumed that on the contact area partly a coition or slippage of crack faces occurs. The problem of the crack equilibrium with partially contacting faces reduces to the problem of linear conjugation of analytic functions. Contact stresses and contact boundaries are determined.

Keywords: isotropic plane in a non-uniform stress field, variable-width crack, contact zones, contact stresses
