Engineering Damage Mechanics is a technical book that focuses on the application of continuum damage mechanics to analyze the failure of mechanical and civil engineering components under various conditions. It addresses aspects such as ductile failure, creep, fatigue, and brittle failure, which depend on thermomechanical loads and the materials used, including metals, alloys, polymers, elastomers, composites, and concrete. To assist both experienced engineers and newcomers, the first two chapters of the book are dedicated to the fundamental concepts of damage mechanics and the associated computational tools. This makes the book a valuable resource for professionals and students dealing with the challenges of material fatigue and failure.
