Equilibrium Mechanical Data of Human Uterine Tissue Measured by Spherical Indentation (updated)

Fang, Shuyang; Myers, Kristin M.

These files contain experimental data from a mechanical study evaluating the four-level, ramp-hold tissue material response to spherical indentation on human uterine samples for 27 locations of 6 uterine samples from 2 uteri. The data in this file correspond to the manuscript entitled, "Anisotropic Mechanical Properties of the Human Uterus Measured by Spherical Indentation", to be published in Annals of Biomedical Engineering in 2021 in the special issue “Advances in Engineering for Women’s Health”. The manuscript is co-authored by Shuyang Fang, James McLean, Joy Vink, Christine Hendon, and Kristin Myers.

The RawData folder contains .csv files corresponding to each tested location. Each file includes the experimental indentation equilibrium force and strain data, and specimen dimensions (length, width and height) – see manuscript for methods. The name of the file indicates the sample ID, which includes the gestation status (NP = nonpregnant, PG = pregnant), the location in the uterus (Ant, Fundus, and Post = anterior wall, fundal wall & posterior wall, respectively), and the relative location in the uterine wall layers (1~6 = outermost layer to innermost layer). For example, “NP_Ant_1.csv” contains the experimental data of the outermost layer of the NP uterine anterior wall.

In these files, the first five rows correspond to the prescribed indentation strain [%], Lagrangian strain e1, e2, and force [N]. The force and prescribed strains are recorded from a universal testing machine, and e1 and e2 are calculated via Vic2D (Correlated Solutions Inc.) using the figures recorded by VicSnap (Correlated Solutions Inc.). The strain data are taken directly under the indenter tip. In the manuscript they correspond to e1_EXP and e2_EXP. The last two rows correspond to the specimen dimensions including the length, width and height. These dimensions are determined using a standard caliper (0.01mm resolution) by measuring along the lines passing through the centroid of the specimen.
