Constitutive models to predict the mechanical performance of sansevieria cylindrica reinforced vinyl ester composite

The research aims to develop a nonlinear regression based mathematical model to predict the mechanical properties of sansevieria cylindrica reinforced vinyl ester composite (SCVEC) and to develop a new micromechanics based Representative Volume Element (RVE) model for predicting the tensile modulus of the SCVEC material. Also, this research focuses on predicting the tensile properties of the SCVEC using theoretical models and correlating it with the empirical results. It was observed that predicted values from the mathematical, numerical and theoretical models were in good agreement with empirical results. It was inferred that NaOH treated 40 mm fibre length, 40 wt. % sansevieria cylindrica reinforced vinyl ester composite shows better mechanical performance compared to the other composite types. SEM micrographs were taken for analyzing the fracture mechanism of the mechanical tested SCVEC material.
