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:
“Love your enemies. I saw this admonition now as simple, sensible advice. I knew I could face an angry, murderous mob without even the beginning of fear if I could love them. Like a flame, love consumes fear, and thus make true defeat impossible.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
