Failure Appraisement
Loering M. Johnson, P.E. (Ret.)
Overview
Failure! Why did it happen? Good question! It
may have happened to a technical product, an economic investment, a biological
condition, or in many other circumstances. Chances are, someone will want to
know why such a failure occurred.
Engineers are frequently called upon to find, or
are faced with the need to know, the reason for a failure. In the course of
your engineering career, you may have on occasion been faced with the task of
determining why, or how, a failure has occurred. Besides the economic issues
associated with such a failure, there may be safety or other important
consequences. Determination of the characteristics of and the reason for
failure may be vital. In order to properly, and successfully, assess failures
it is necessary to follow a suitable procedure.
This course describes principles and techniques that are helpful
in guiding a successful failure appraisal.
The student must take a multiple-choice quiz consisting of fifteen (15) questions at the end of
