Effect of strain rate on the fracture behaviour of collagen
- 108 Downloads
The strain-rate dependence of collagen fibre, a viscoelastic material, was studied both in the native and dry conditions. The strain rate effect was observed in the stress-strain, plastic set behaviour of both dry and wet collagen fibres. Fractured ends of the broken fibres, observed using scanning electron microscopy, showed that the fracture behaviour was different at high and low strain rates. The results are compared with those for elastoidin.
