A study is made of radial crack evolution in curved brittle layers on compliant support substrates. Three-dimensional boundary element analysis (BEA) is used to compute the stepwise growth of radial cracks that initiate at the bottom surfaces of glass on

Growth habits and defects in epitaxial ZnO nanowires grown from Au catalyst on (0001) GaN/sapphire substrate using Vapor-Liquid-Solid (VLS) technique were studied using electron microscopy and X-ray diffraction. The results revealed presence of both
The competition between fracture modes in monolithic brittle materials loaded in cyclic contact in aqueous environments with curved indenters is examined. Three main modes are identified: conventional outer cone cracks, which form outside the maximum
