Abstract

This contribution presents a hybrid analytical-numerical treatment of the thermo-mechanical model for the analysis of the braking process of rotating machine parts such as wheels, etc. The machine parts have the shape of a thick disk. These disks are repeatedly frictionally disk-braked at random sequences of time instants. As the loading is rather severe, the stresses during braking and subsequent cooling reach the plastic limits in compression and tension, respectively. Hence, the loading may cause conditions similar to those encountered in shake-down phenomena.

Article
A comprehensive treatment of fracture mechanics suitable as a graduate text and as a reference for engineers and researchers is presented. The general topics addressed include: fundamental concepts of linear elastic and elastic-plastic fracture mechanics; dynamic and time-dependent fracture mechanics; micromechanisms of fracture in metals and alloys; fracture mechanisms in polymers, ceramics, and composites; applications to fracture toughness testing of metals and nonmetals, to structures, fatigue crack propagation, and computational fracture mechanics. Reference materials usually found in fracture mechanics handbooks is provided.
