Hyperelastic Material Properties of Mouse Skin under Compression
Figure 6
Summary of procedures for measuring and calculating hyperelastic skin material properties.
(A) Example plot of force and displacement versus time. Illustration of SIF compensation of force traces, where interval A is the interval picked for curve-fitting in compensating error caused by SIF, and contact point B. Solid black line: force. Dashed gray line: displacement. Dashed black line: curve fit for SIF compensation. (B) Schematic force vs. displacement plot. k0 is the slope of the linear region, which indicates the initial stiffness of skin. (C) Schematic stress vs. change in stretch plot. E0 is the slope of the linear region, which indicates the initial Young's modulus of skin.
