Surface and subsurface cracks and pores with liquid under action of a contact load in the presence of a lubricant

摘要: The problem for a half-plane which contains some straight surface and subsurface cracks pores with non-compressible liquid is formulated. boundary experiences normal frictional stresses that are transmitted through lubricant. prestressed by tensile/compressive residual the shape of containing changes during contact load motion along surface. As result, cavities intervals contacting edges created. can be fully or partially filled lubricant liquid. conditions expressed various configurations (closed open to tips cracks, splitting gathering partly liquid). These problems reduced systems integro-differential equations in form alternating equalities inequalities solved means perturbation numerical methods.
