Principles of Loads and Failure Mechanisms

Failure of components or systems must be prevented by both designers and operators of systems, but knowledge of the underlying mechanisms is often lacking. Since the relation between the expected usage of a system and its failure behavior is unknown, unexpected failures often occur, with possibly serious financial and safety consequences.

Principles of Loads and Failure Mechanisms. Applications in Maintenance, Reliability and Design provides a complete overview of all relevant failure mechanisms, ranging from mechanical failures like fatigue and creep to corrosion and electric failures. Both qualitative and quantitative descriptions of the mechanisms and their governing loads enable a solid assessment of a system's reliability in a given or assumed operational context.

Moreover, a unique range of applications of this knowledge in the fields of maintenance, reliability and design are presented. The benefits of understanding the physics of failure are demonstrated for subjects like condition monitoring, predictive maintenance, prognostics and health management, failure analysis and reliability engineering. Finally, the role of these mechanisms in design processes and design for maintenance are illustrated.

Tiedo Tinga holds a PhD in Mechanical Engineering (Eindhoven University of Technology) on the development of a micro-mechanical model for Ni-base superalloys in gas turbine blades.

He has been working as a senior scientist at the National Aerospace Laboratory NLR in the Netherlands for almost 10 years. There he ran several research projects in the field of computational mechanics, mainly concerning life assessments of airframe and gas turbine components. Since 2007 he is an associate professor in Maintenance Engineering at the Netherlands Defence Academy and thus involved in the education of future officers for the Dutch Navy, Air force and y. He is also leading the research program on maintenance of military systems, which aims to combine scientific research to innovative maintenance concepts with practical applications within the ministry of Defence. In 2012 he has been appointed as full professor Dynamics Based Maintenance at the University of Twente. He now combines this chair with his position at the Defence Academy.
