This research focused on the mathematical model that could be simplified as the series function. This function used for macroscopic explanation of the relationship between shear modulus and Brinell hardness of fibrous composites. Kraft paper was used as the sample for this testing. The paper-grammage was varied as following:150, 230, and 420, whereas, the dwell time of indentation was ranging as: 10, 20, and 30 seconds, respectively. And then, the correlation between shear modulus (G) and Brinell Hardness Number (BHN) was obtained by using the simulation of experimental results. These were collected by the Brinell hardness testing machine. After that, the refitting process was analyzed using the polynomial based on linear and quadratic model, respectively. It was found that the interpretation of G-BHN relation using the quadratic be better than the linear one. Because of the coefficient of determination (R2) that analyzed by quadratic function present in higher value than another one. |
