Abstract :
This work introduces a tutorial series on material failure mechanisms and
damage models to familiarize nonspecialists with the fundamentals of failure
mechanisms in engineering assemblies. Since failure is a complicated
concept, four simple conceptual models for failure are discussed:
stress-strength, damage-endurance, challenge-response, and
tolerance-requirement. The specific failure mechanisms depend on material or
structural defects, damage induced during manufacture and assembly, and on
conditions during storage and field use. Conditions that affect the state of
an item are broadly termed stresses (loads), e.g., mechanical stress and
strain, electrical current and voltage, temperature, humidity, chemical
environment, and radiation. The effects of stresses are influenced by
geometry, constitutive and damage properties of the materials, manufacturing
parameters, and the application environment.
