WebOct 16, 2008 · Abstract Fracture modes in a model glass/polymer coating/substrate system indented with hard spheres are investigated. The large modulus mismatch between the glass and polymer results in distinctive transverse fracture modes in the brittle coating: exaggerated circumferential (C) ring cracks that initiate at the upper coating surface well … Webthe brittle coating and into the underlying substrate. In-dentation loads are much larger than in the previous test and are typically in the range of 0.6 to 1.5 kN. Plastic deformation of the substrate forces the coating to be dis-placed radially, inducing a compressive radial stress in the coating that decreases with increasing distance from
