On the risk of fatigue in extension spring hooks

$15.00

This paper describes one of the results of research conducted with the European Collective Project “Techspring”. Extension springs with integral hooks were manufactured and tested so as to establish the hook diameter at which the hook is not vulnerable to fatigue failure. These results have been integrated into spring design software and will be useful to all manufacturers and users of extension springs.
