EFFECT OF STRAIN-RATE ON CROSS-LINKED COLLAGEN-FIBERS

Mechanical properties such as stress-strain relationships, plastic set and fracture behaviour were studied for chrome and formaldehyde tanne d collagen fibres. The stress-strain and fracture behaviour were found to be different from that of untanned collagen fibres, whereas the pl astic set showed only marginal differences. The morphology of the frac tured ends of the fibres tested at different strain rates was studied using scanning electron microscopy. An attempt has been made to clarif y the different patterns of the cross-linked collagen fibres.
