| Résumé : |
Leather exhibits a complicated mechanical behavior that can be best explained by using concepts of theoretical viscoelasticity. To permit a mathematical description of the time dependent properties of leather under different testing conditions, springs and dashpots are used. A six-element model comprised of three Maxwell units in parallel satisfactorily described stress-relaxation properties of leather. Scanning-electron micrographs reveal that fibers remain desegregated upon drying of leather in the presence of fatliquor, while stress-relaxation tests show that relaxation moduli and relaxation times decrease with increase in fatliquor content as well as with increase in temperature and moisture content. The results obtainable by the stress relation method should find application in process control, specification acceptance and service evaluation. |
