Notes: An indepth biomechanical study was performed to characterize more fully the viscoelastic behavior of post-rigor bovine muscle, using samples oriented parallel and perpendicular to the muscle fiber direction. Two enzymes were used to degrade the intramuscular connective tissue (IMCT) to evaluate its mechanical contribution. An unusual stress-strain curve was found in the parallel oriented samples, with enzymolysis affecting the curve at strains larger than 8%. Reductions in stresses in both orientations due to enzymolysis were 50% with extensibility unchanged. Stress relaxation tests indicated that regardless of orientation or treatment the relative stress-relaxation was unchanged. IMCT contributed substantially to the mechanical response only at large deformations.

Notes: The effects of polymer impregnation, moisture, and lubricant oils on the complex modulus of the grain layer of leather have been studied. The impregnated materials were prepared by introducing a mixture of polyurethane oligomer and vinyl monomers into the grain layer and polymerizing by electron-beam irradiation. Synergism was observed in the interaction of the components of the system and analyzed in terms of the adhesion of the polymer to the collagen fibers.
