Kurzbeschreibung (Abstract)
In-situ crack propagation studies using the scanning electron microscope (SEM) on seven materials are used to define three general categories for crack bridging elements: intact (elastic) bridges, frictionally sliding (plastic) bridges and mechanically interlocked (elastic-plastic) bridges. A number of examples are provided, some including sequences detailing bridge formation and bridge evolution. Failure modes of all these restraining elements, their interrelations and synergistic effects are discussed.
A simple fracture mechanics model attempts to provide the criteria for bridge formation. The relevant microstructural parameters are grain size and shape, intra- or intercrystalline fracture energy, residual stress and Young's modulus.
