Parameter Identification of Hysteretic Models using Partial Curve Mapping

This paper describes a new method for curve matching essential to the solution of inverse problems represented by material parameter identification. Hysteretic response curves are specifically addressed as a general class. The method is based on Partial Curve Mapping (PCM) of the experimental and computed curves. This methodology involves a curve matching metric which is computed using the volume between the test curve and the computed curve section. A number of examples are presented to demonstrate the capability.
