Rheology, Physical and Mechanical Behavior of Materials 5 studies fractures and fatigue in metallic materials and composites. It analyzes the mechanisms at work according to the types of damage and fractures observed. This book covers the formation of cracks around inclusions or precipitates, ductile and cup fracture facies, abrupt or intergranular fractures, cleavage and the influence of strain rates in striction and fracture. It also looks at the formability limit curves of metals under dynamic actions and techniques used. Regarding metals, the book studies the types of tests, cracking mechanisms, and laws relating to uncracked and cracked parts, as well as endurance limits. As for composites, fracture mechanisms for unidirectional and laminate materials, successive layer fractures, maximum and quadratic stress and/or strain criteria, and fracture envelopes are analyzed.
