A Preisach model for hysteretic description of natural maize composites
Keywords:
composites, natural fiber, hysteretic behaviour, Preisach model, Bouc-Wen modelAbstract
The work is focused on the hysteretic behavior of a composite made out of stalk based maize fiber and unsaturated polyester resin polymer as matrix with methyl ethyl ketone peroxide as a catalyst and Cobalt Octoate as a promoter. A Preisach model is used to describe the behavior of such composites subjected to stretchingcompression cycles. A procedure for fitting the Bouc-Wen model to imitate experimental data, are presented and discussed together with the Preisach model.
