A BSTRACT . The paper addresses an actual fundamental mechanical problem – analysis of deformation behavior of a perfectly bonded layered metallic composite consisting of soft and hard components, being subjected to normal load and shear stress under mechanical equilibrium at prohibited interfacial slip. The problem is solved with the use of 3D crystal-plasticity (CP) simulations using the DAMASK Spectral Solver package. By doing so, microstructure-inherited stress and strain fields were calculated, visualized, and analyzed. The results obtained provide an insight into the patterns of stress and strain localization as well as their evolution within and between mated soft/hard phases with different microstructure at the onset of subsurface deformation processes. The latter corresponds to the pre-sliding regime beneath dry tribological contact zones. The resulting effective shear-to-normal stress ratio responses exhibited significant differences that depend on the microstructure and mechanical properties of both interfaced materials that compose a tribological pair.
