A push (reverse pull) test is a method where the principal goal is to apply a downward load onto a sample to measure response as a function of applied downward load. This downward load may be destructive (to part failure) or non-destructive (to force threshold) as needed. For non-destructive tests, force may be applied once or cyclically to evaluate part performance over repeated loading cycles. Most common example of push test: 3-point and 4-point bending and pin test applications.
