Effects of Damage on Interfacial Crack Tip Fields

Abstract

Under applied stress, damage occurs by separation of the matrix from the hard particles. Damage can occur during processing, transpiration, and storage. After the damage event, removal of stresses may conceal this type of damage. The size and extent of damage may be difficult to assess. Damage can determine whether a nearby crack grows, and if so, how it grows (both trajectory and speed). Cracks can promote uneven burning and can alter propulsion behavior, resulting in inaccurate delivery of payload. Catastrophic destruction of both rocket and payload is possible. Collateral damage to surrounding equipment and personnel is also possible.
