Abstract
We analyze stress softening phenomena within the framework of the 'generali zed standard material' based on the notion of a 'normal dissipative mechani sm'. We prove that the monotonicity properties of the 'yield function' gove rning such mechanism lead to local and global uniqueness of the response. A pplications to oscillators with a single degree of freedom, whose anharmoni c spring exhibits stress softening, are also presented. (C) 2001 Editions s cientifiques et medicales Elsevier SAS.
