Modeling Asymmetric Hysteresis: Continuous Development Using Experimental Data

Modeling asymmetric hysteresis is challenging, especially when computational efficiency is sought. This study continues with an effort to capture asymmetric hysteretic restoring force as motivated, inspired, and validated by a set of carefully designed and acquired laboratory experimental data at Sapienza University of Rome. With improved testing apparatus, richer datasets deliver more comprehensive views of the asymmetric hysteresis behaviors, making it possible to further advance the proposed generalized extended Masing model involving the virgin loading curve and minor loops.
