APLICAÇÃO DO ELEMENTO FRACIONÁRIO DE NEWTON AO FLUIDO COMPLEXO DE EQUISTAR PETROTHENE NA 952-00: NOVAS PERSPECTIVAS DE ESTUDO

Abstract

The Scott-Blair model, also known as Newton’s Fractional model, will be used in this study to model the relaxation modulus, the compliance creep modulus and the dynamic modulus of Lyondell Basel’s LDPE resin (Equistar Petrothene NA 952-00).  It is evident that the adjustment made in this study are practically close to the experimental data, with correlation values close to 0,99. The phase angle is the weakness of the model. It was also verified in this work a similarity with the CIEL*a*b system. For the resolution of the work the commercial tool Excel was used.
