We analyze stress softening phenomena within the framework of the 'generalized standard material' based on the notion of a 'normal dissipative mechanism'. We prove that the monotonicity properties of the 'yield function' governing such mechanism lead to local and global uniqueness of the response. Applications to oscillators with a single degree of freedom, whose anharmonic spring exhibits stress softening, are also presented.

Abstract
We analyze stress softening phenomena within the framework of the 'generalized standard material' based on the notion of a 'normal dissipative mechanism'. We prove that the monotonicity properties of the 'yield function' governing such mechanism lead to local and global uniqueness of the response. Applications to oscillators with a single degree of freedom, whose anharmonic spring exhibits stress softening, are also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
