Reliability is the ability of a product to perform as intended (i.e., without failure and within specified performance limits) for a specified time, in its life cycle application environment. The physics-of-failure (PoF) approach to reliability utilizes knowledge of the life-cycle load profile package architecture and material properties to identify potential failure mechanisms and to prevent operational failures through robust design and manufacturing practices. Reliability assessments based on physics-of-failure methods incorporate reliability into the design process providing a scientific basis for estimating product life under actual operating conditions.

This course introduces the classical reliability concepts and relates the concepts to the physics of failure approach. The information provided in this course will be useful for implementing a physics-of-failure methodology for the life cycle of a product. The participants will learn how to develop and migrate to physics-of-failure based reliability assessment programs. The course will also teach how to facilitate the introduction of the physics-of-failure methodology among the complete supply chain of the product.
