要約

Special features of deformation and fracture of a material with coating of different thickness in tension have been investigated. The boundary-value problem in the plane-strain formulation is solved numerically by the finite-difference method. In calculations, a composite structure is taken into account explicitly. It is found that for thick coatings, a value of stress concentration near the "coating−base material" interface does not change with changes in the coating thickness whereas in the region of small thicknesses it increases nonlinearly with a decrease in the coating thickness. This effect is observed at the elastic stage of composite deformation, it enhances as plastic deformation develops in the base material, and amounts to 25% at the prefracture stage. Recommendations that could be useful for optimization of the coating thickness are given.
