The materials mechanics of the controlled separation of a body into two or more parts – cutting – using a blade or tool or other mechanical implement is a ubiquitous process in most engineering disciplines. This is the only book available devoted to the cutting of materials generally, the mechanics of which (toughness, fracture, deformation, plasticity, tearing, grating, chewing, etc.) have wide ranging implications for engineers, medics, manufacturers, and process engineers, making this text of particular interest to a wide range of engineers and specialists.
