How would you define destructive testing?
Tests are carried out to the specimen's failure, in order to understand a specimen's performance or material behavior under different loads.
Tests are carried out to the specimen's failure, in order to understand a specimen's performance or material behavior under same loads.
Tests are carried out to the specimen's failure, in order to understand a specimen's performance or material behavior without loads.

What is the main idea of stress testing?
It used to test situations and detecting the failure which can be accomplished using a sound detector or temperature gauge which produces a signal to trigger the high-speed camera.
