Crack dynamics and crack surfaces in elastic beam lattices... Introduction of disorder leads, however, to the formation of the “mirror-mist-hackle”–type interface typical in many experimental situations.Peer...
Prediction of fracture energy and flaw size in glasses from measurements of mirror sizeFracture strengths (u), fracture-initiating flaw sizes, and mir-ror radii ( r) , as outlined by either the mist or the hackle bound-ary, were measured for silicate and nonsilicate glasses (e.g....
Ballistic perforation of graphite/epoxy composite... The scanning electron microscopic examination of the fragments from the impact shows that the fracture surfaces of the matrix have some characteristic hackle marks....
Fractographic failure analysis of a procera allceram crown using stereo and scanning electron microscopy... Specific sites of interest identified under the stereo microscope were analyzed using the SEM at high magnifications searching for small fracture features such as wake hackle and twist hackle within the veneering ceramic in order to confirm the direction of crack propagation....
