Destructive Testing
Destructive testing is
testing which destroys or physically changes the
configuration of the object being tested. After
destructive testing the object may not be usable as
originally designed/intended. Examples of
destructive testing include (but are not limited to)
tensile testing, metallography, impact testing, chemical analysis, etc.
It is a process where load or
stress is applied to the object of interest until
the test specimen fails. These tests are generally much
easier to carry out, yield more information, and are
easier to interpret than the result of non-destructive testing.
Nondestructive testing
of an object is often done in
view of future use, which would make destructive
testing pointless. However, destructive testing can be useful if the
result gives information about similar specimens
which are not tested.
