| Résumé : |
Since leather is sold by the square foot, destructive tests lessen the square footage of the material and infringe on the leather manufacturer's total profit. Therefore there is a need for developing an instrument to perform nondestructive testing of the physical properties of leather. In this investigation, experiments were designed to pass leather test samples through a pair of rotational acoustic sensors, thereby enabling the collection of acoustic emission (AE) signals from both the grain and corium and provide a more accurate assessment of the quality of leather. Observations showed a strong correlation between the mechanical properties of leather and the corresponding cumulative acoustic energy. We also used this dynamic method to characterize the grain break of leather. Results showed that the difference in grain break could be determined form the amount of acoustic hits collected from moving the AE sensors over a leather sample. Observations showed the poorer the grain break ; the more AE energy was detected. Data also demonstrated that thicker samples tended to have poorer grain break. In short, this study demonstrated that the tensile strength, stiffness, toughness ans grain break could be nondestructively determined by measuring acoustic quantities with a pair of rotational sensors. |
