Impact testing provided an order of magnitude faster test time and minimal fixtures.
As a result, it became a very good field-testing and troubleshooting
method, as well as a pretesting method for controlled laboratory
testing. This article is a general review of the evolution of impact
testing from its development in the 1960s and ’70s to the present
time, with a more extensive review of recent developments in test-
ing procedures and parameter estimation for multiple-reference
impact testing (MRIT).
