Figure 1: Relationship of normal stress to shear strain for semiflexible and flexible polymer hydrogels. The negative normal stress is not unique to fibrin, but is seen for all measured gels formed ...
Principal stresses are defined as the maximum and minimum normal stresses in a plane. Principal stresses are perpendicular to each other and oriented such that shear stresses are zero. For 3D stress ...
The stress value then levels off at the equilibrium value (Figure 7). Figure 7. Illustration showing the stress evolution of a yield stress material at constant shear rate. Normally, a low value of ...
