MODELING AND IDENTIFICATION OF INELASTIC SYSTEMS USING THE ENDOCHRONIC MODEL

An effective modeling method is proposed for the endochronic model bas ed on the concept of plastic equilibrium points, which reduces the num ber of parameters involved and greatly simplifies the modeling process for practical applications. A systematic, optimization-based paramete r estimation procedure for the proposed class of endochronic models is also presented for identification studies. Validity of the proposed m odeling technique in both modeling and identification of inelastic sys tems is demonstrated by biaxial tension-torsion applications using exp erimental results available in the literature.
