Abstract

The interfacial mechanisms of the stress concentration in materials with modified surface layers are investigated. A dynamic boundary-value problem in a plane-strain formulation is solved numerically by the finite-difference method. Serrated and wavy base material-surface layer interfaces observed experimentally are assigned explicitly in calculations. Two stages in the evolution of the stress concentration are found to occur due to irregular interfacial geometry. The stress concentration in near-interfacial regions turns out to depend on the sinusoidal wavy interface thickness and roughness.
