Interface defeat is when a ceramic armour system, typically on an armoured fighting vehicle, defeats a kinetic energy penetrator at the ceramic's front surface. Above a certain impact velocity, known as the transition velocity, interface defeat can no longer occur and either penetration or perforation of the ceramic occurs.
Famous quotes containing the word defeat:
“Mrs. Van Hopper: Most girls would give their eyes for a chance to see Monte.
Maxim de Winter: Wouldn’t that rather defeat the purpose?”
—Robert E. Sherwood (1896–1955)
