Effects of a Pseudophysiological Environment on the Elastic and Viscoelastic Properties of Collagen Gels

Figure 2

Example of a stress-strain curve obtained from a tensile test on a preconditioned collagen gel (10 cycles of loading and unloading) in air at 23°C. Linear modulus was calculated from the slope of the linear regression. The linear regression was determined by successively adding points in data in the left direction (starting from the point at rupture) as long as the squared R was >0.990.
