Structural change of collagen network under shear, and double stress relaxation tests for purified fibrin gels. (A) Images of a collagen gel taken by confocal reflectance on the x–y plane (schematic) before, during, and after shear deformation with fibers detected from the image processing overlaid in red. Double stress relaxation tests with positive and negative strains were conducted for purified fibrin (B) without equilibration time and (C) with containing equilibration time between steps.
