The load-displacement curve of a set of disc springs shows a hysteresis due to structural damping. A method has been proposed to retard tearing instability of structures such as piping systems, by using the disc spring as a supporting member for the structures. The condition has been described theoretically for tearing instability under structural damping. The slope of the curve in unloading has been shown to be a key parameter for the tearing instability. Tensile testings of cracked specimens loaded in series with the spring have shown a tearing instability depending on the structural damping and have verified the condition. It has been proved that the retardation of tearing instability is possible with the use of the disc spring with structural damping.
