Biaxial Mechanical Data (Young and Aged Mice, Ventral and Dorsal)

This data set contains the biaxial tension data of mouse skin. It contains 111 total .csv files that provide information on how the data was collected. All data is with respect to the in vitro unloaded reference configuration (see Figure 1 in the description file). The file name provides details on the sample including subject number, sample number, subject age (i.e., young = 12 weeks, aged = 52 weeks), and sample location (i.e., dorsal or ventral). Each data sets contains three .csv files, each labeled and representing one of the three loading configurations – Equibiaxial (1:1 stretch ratio between 11 and 22 direction), OffbiaxialX (1:2 stretch ratio), and OffbiaxialY (2:1 stretch ratio), determined by rake-to-rake displacement in a displacement-controlled test. Every .csv file contains 4 columns. Columns one and two contain the DIC acquired stretches (unitless) of the tissue in the 11 and 22 direction, respectively. Columns three and four contain the Cauchy stresses (in MPa) in the 11 and 22 direction, respectively. Note, the anatomical lateral direction is the 11 direction and anatomical cranial-caudal direction is the 22 direction. These data represent the experimental downstroke data after 5 cycles of preconditioned loading, at a strain rate of approximately 1.25%/s (approximated during testing by rake-to-rake distance), in 37°C 1xPBS. Thickness of tissues for stress calculations were determined via transverse sections in optimal cutting temperature medium post-testing.
