| Résumé : |
Tearing tests were performed along with tensile tests on chrome-tanned leather to clarify the difference between the teraing and tensile behaviors and their fracture mechanisms. For the tearing tests, a unique zigzag fracture pattern was observed due to the fluctuations in the tearing force, whereas the tensile tests demonstrated a uniform fracture pattern. Observations also showed that strain rate does not significantly affect tearing strength, but slightly affects tensile strength. Both strengths increase with increasing moisture content until certain levels, beyond which they start to decrease with increasing moisture content. A drastic difference between these two strengths is demonstrated in their response to sampling angle change. Tearing strength showed little variation with the change of sampling angle, whereas the tensile strength was maximum when sampled parallel to the backbone, then steadily decreased when sampling angle deviated from the backbone line. Statistical analysis showed that the tensile strength did not correlate well to tearing strength, whereas a good correlation was observed between fracture energy and tearing strength. |
