Modeling Elastic and Geometric Properties ofCoffea arabicaL. var.ColombiaFruits by an Experimental-numerical Approach

In this study, different approximations are computed for the geometrical and elastic properties of fruits Coffea arabica var. Colombia. By using experimental data of size, volume, and Young’s moduli (semi-experimental), numerical and analytical investigations are carried out to analyze the behavior of these parameters during ripening. Further, new equations are proposed that describe the volume and Young’s modulus in function of the orthogonal diameters (,, and ) and ripening time. The models were in good agreement with the experimental data reported in the literature. Potential applications of the volume model could be explored in in situ identification of the ripening time of the fruits, as well as the evaluation of productivity associated with the studied coffee variety.
