"The stress-strain relations of thermally sprayed ceramic coatings are strongly nonlinear. Under compressive stresses, elastic closing of microcracks leads to a gradual decrease of the microcrack density and to an increase of Young\u2019s modulus in compression. Under tensile stresses, the microcracks slightly grow by inelastic processes; the microcrack density gradually increases and effective Young\u2019s modulus in tension decreases. A two-parametric equation containing linear and quadratic terms is used to describe the nonlinear stress-strain curves. The fracture of ceramic coatings at higher tensile stresses due to coalescence of the microcracks is discussed." . "1059-9630" .
