Destructive testing
In destructive testing (or destructive physical analysis, DPA) tests are carried out to the specimen's failure, in order to understand a specimen's performance or material behavior under different loads. These tests are generally much easier to carry out, yield more information, and are easier to interpret than nondestructive testing.
Applications
Destructive testing is most suitable, and economic, for objects which will be
Analyzing and documenting destructive failure mode
Analyzing and documenting the destructive failure mode is often accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture almost any type of destructive failure.[1] After the failure the high-speed camera will stop recording. The captured images can be played back in slow motion showing precisely what happens before, during and after the destructive event, image by image.
Methods and techniques
Testing of large structures
Testing of structures in earthquakes is increasingly done by modelling the structure using specialist
Software testing
Destructive software testing is a type of software testing which attempts to cause a piece of software to fail in an uncontrolled manner, in order to test its robustness and to help establish range limits, within which the software will operate in a stable and reliable manner.
Automotive testing
Automobiles are subject to crash testing by both automobile manufacturers and a variety of agencies.
Aircraft testing
There has also been extensive destructive testing of passenger and military aircraft, conducted by aircraft manufacturers and organizations like
