Experimental Characterization of the Non-Linear Viscoelastic Properties of Human Female Perineal Tissue

The dataset contains raw data from stress-relaxation and ultimate tensile tests performed on post-mortem human female perineal tissue using a Zwick/Roell biaxial testing machine operated in uniaxial mode. The following variables are included: Time – Duration of the experiment (in seconds). Displacement X – Combined displacement of the two axes in the x-direction. Displacement Y – Combined displacement of the two axes in the y-direction. Force X – Combined force from the two axes in the x-direction. Force Y – Combined force from the two axes in the y-direction. Absolute Position Axis 1 - 4 – Position of each axis (1 to 4), measured from the pre-defined machine setup. Absolute Displacement X – Combined displacement in the x-direction, calculated using the absolute positions of the relevant axes. Absolute Displacement Y – Combined displacement in the y-direction, calculated using the absolute positions of the relevant axes. Force 1 - 4 – Force measured individually on axes 1 to 4. Relative Position Axis 1 - 4 – Position of each axis (1 to 4), with the starting position at 0 mm.
