DYNAMIC STRESS CONCENTRATION FACTORS

Abstract

The problem of the response of structural discontinuities to short duration pulses is studied experimentally. Employing explosively induced stress pulses in thin plastics pulsates containing central circular holes, a dynamic stress concentration factor is determined as a function of pulse frequency. It is concluded for this loading case that the dynamic stress concentration is significantly lower than the static value.
