There are a wide range of books available on the cutting of metals, but no other text is devoted to the cutting of materials generally, the mechanics of which (toughness, fracture, deformation, plasticity, tearing, grating, chewing, etc) havCuttingDeformations (Mechanics)Fracture mechanicsMaterialsMechanical propertiesCutting.Deformations (Mechanics)Fracture mechanics.MaterialsMechanical properties.620.1Atkins Anthony G.1939-1442320MiAaPQMiAaPQMiAaPQBOOK9911004798503321The science and engineering of cutting4391980UNINA
