A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascading systems failure. The term is most commonly used for structural failures, but has often been extended to many other disciplines in which total and irrecoverable loss occurs, such as a head crash occurrence on a hard disk drive. Such failures are investigated using the methods of forensic engineering, which aims to isolate the cause or causes of failure. In chemical engineering, thermal runaway can cause catastrophic failure.

  • A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascading systems failure. The term is most commonly used for structural failures, but has often been extended to many other disciplines in which total and irrecoverable loss occurs, such as a head crash occurrence on a hard disk drive. Such failures are investigated using the methods of forensic engineering, which aims to isolate the cause or causes of failure. For example, catastrophic failure can be observed in steam turbine rotor failure, which can occur due to peak stress on the rotor; stress concentration increases up to a point at which it is excessive, leading ultimately to the failure of the disc. In firearms, catastrophic failure usually refers to a rupture or disintegration of the barrel or receiver of the gun when firing it. Some possible causes of this are an out-of-battery gun, an inadequate headspace, the use of incorrect ammunition, the use of ammunition with an incorrect propellant charge, a partially or fully obstructed barrel, or weakened metal in the barrel or receiver. A failure of this type, known colloquially as a "kaboom", or "kB" failure, can pose a threat not only to the user(s) but even many bystanders. In chemical engineering, thermal runaway can cause catastrophic failure. (en)
  • Uma falha catastrófica é um fracasso repentino e total, do qual a recuperação é impossível. Falhas catastróficas, muitas vezes, levam a uma . O termo é mais comumente usado para , mas muitas vezes tem sido estendido a muitas outras disciplinas das quais a perda total e irrecuperável ocorre. Tais falhas são investigadas através de métodos de engenharia forense, que tem como objetivo isolar a causa ou causas da falha. Por exemplo, uma falha catastrófica pode ser observada em uma falha no rotor de turbina a vapor, que pode ocorrer devido ao pico de estresse no rotor; a tensão concentrada aumenta até um ponto em que ela é excessiva, culminando em uma falha do disco. Em armas de fogo, uma falha catastrófica geralmente refere-se a uma ruptura ou a desintegração do cano da arma ao atirar. Algumas possíveis causas disso são o uso incorreto de munições, o uso de munições com uma carga incorreta de propelente, cano parcialmente ou totalmente obstruído, ou o enfraquecimento do metal do cano. Uma falha deste tipo, conhecida coloquialmente como "kaboom", ou falha "kB", pode representar uma ameaça não apenas para o usuário, mas até mesmo para as pessoas ao redor. Em engenharia química, um pode causar uma falha catastrófica. (pt)
