The effect of varying thickness and constant surface area (R = 1) and pressure (4 kPa) on (A) pelvic floor displacement and (B) Von Mises stress. For thicknesses of 1 to 3 mm, the pelvic floor deflected most strongly (up to 60 mm), whereas beyond a thickness of 3 mm, displacement decreased more gradually (A). Similar behavior was observed for stresses (B). The range of 1 to 12 mm roughly corresponds to the variation in thickness across the pelvic floor and among individuals reported in the literature (SI Appendix, Table S1). The thickness of the base model is 6 mm.
