© 2021. This work is licensed under a [CC BY 4.0 license][1]. The dataset is composed of: 1. list of models used in the first three experiments of this study and their dimensions are summarized in the "Experiments and Models.docx" file; 2. geometries used for modeling are available under the "Geometries" folder as .stl files; and 3. the exported data from the FEA analyses using the [FEBio][2] software are available under the "Exported Data" folder. Each of the four Excel files contains dimensions of models in the first column. The model filenames have the following structure: "Model-ML-AP-thickness" (ML - mediolateral, AP - anteroposterior dimensions). The displacement magnitudes reported in this study (see main text) are computed as the average displacement magnitude of six elements in the region of interest. The displacement magnitude of each element is computed at its centroid as the $\sqrt{(\delta_y^2 + \delta_z^2)}$, where $\delta_y$ and $\delta_z$ are displacements in mm in y and z directions, respectively. The displacement in the $x$ direction is negligible; hence it is not used in computing the displacement magnitude. The stretch $\lambda$ is computed as $\sqrt{2*(\varepsilon) + 1}$, where $\varepsilon$ is the Lagrangian strain of the material. The transverse size of the pelvic floor R is defined as the $\sqrt{(SA_{current}/SA_{base})}$, where $SA_{current}$ is the measured surface area of the current model and $SA_{base}$, is the surface area of the base model.
