Abstract
The problem related to the determination of the borderline between elastic/plastic shakedown and incremental/instantaneous collapse domains in the Bree diagramfor elastic perfectly plastic structures subkected to a combination of fixed and perfect cyclic load is studied. The relevant boundary is determined taking into account suitable limits related to the structures ductility features. In particular, basing on a special bounding theorem, it is possible to introduce appropriate boundary constraints on chosen measure of the plastic strains occurring at the end of the transient phase of the structural responseI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
