Unconstrained Optimization and Calibration of a Kinematic-Cyclic Plasticity Model

Abstract

In this paper, a mixed kinematic and isotropic cyclic plasticity model based on the concept of Fuzzy Set Plasticity, which is a versatile technique for modeling a range of complex phenomena observed in non-proportional loading in soil-structure interaction, is implemented. It is followed by a discussion of associated model parameters and model parameter sensitivity analysis. The use of zero-order numerical optimization techniques is discussed and its application in calibrating the Fuzzy Set Plasticity Model is presented. The performance and comparison among these numerical optimization schemes are also examined and discussed.
