The problem on indentation of elastic area with layered coating by cone shaped indenter is studied. Corresponding layers as well as material area are described using different models such as bilinear and Drucker-Prager model. As a result, the study covers materials of different nature described by completely different mechanical behavior under hydrostatic load. Various cases of elastoplastic properties for each layer are considered including the phenomena of residual stresses appearing after unloading and delaminating defects caused by stress concentration at the interface between layers.
