Studies on the Failure of Metal Mechanical Joints Subjected to Dynamic Loads

Abstract

A series of experimental dynamic tests were conducted on riveted joints and struts with central holes to establish quantitatively fracture mechanisms and to determine dynamic load factors based on measured strains. Results of these experimental tests on aluminum struts with a central circular indicate that dynamic stress concentrations associated with the hole are approximately equal to the static stress concentrations for the same specimen. Riveted joints subjected to dynamic loadings exhibit the same general fracture/ failure modes associated with similarly static loaded riveted joints. Dynamic response of riveted joints and subsequent fracture is very dependent on the joint stiffness and loading history.
