Around 80% of women experience vaginal tears during labour when the diameter vagina must increase to allow passage a full-term baby. Current techniques for evaluating are qualitative and often lead an incorrect diagnosis inadequate treatment, severely compromising quality life women. In order characterize failure properties tissue, whole tracts from rats (n = 18) were subjected free-extension inflation tests until rupture using custom-built experimental set-up. The resulting deformations...
Vaginal tears are very common and can lead to severe complications such as hemorrhaging, fecal incontinence, urinary dyspareunia. Despite the implications of vaginal on women's health, there currently no experimental studies tear behavior tissue. In this study, planar equi-biaxial tests square specimens tissue, with sides oriented along longitudinal direction (LD) circumferential (CD), were conducted using swine animal model. Three groups mechanically tested: NT group (n = 9), which had...
The vagina undergoes large finite deformations and has complex geometry microstructure, resulting in material geometric nonlinearities, complicated boundary conditions, nonhomogeneities within element (FE) simulations. These nonlinearities pose a significant challenge for numerical solvers, increasing the computational time by several orders of magnitude. Simplifying assumptions can reduce significantly, but this usually comes at expense simulation accuracy. This study proposed use reduced...
The vagina is a viscoelastic fibromuscular organ that provides support to the pelvic organs. properties of are understudied but may be critical for stability. Most studies evaluate vaginal viscoelasticity under single uniaxial load; however, subjected dynamic multiaxial loading in body. It unknown how varied conditions affect behavior and which microstructural processes dictate response. Therefore, objective was develop methods using extension-inflation protocols quantify creep various...
Significance: The spatial organization of collagen fibers has been used as a biomarker for assessing injury and disease progression. However, quantifying this complex structures is challenging. Aim: To quantify classify fiber organizations. Approach: Using quantitative second-harmonic generation (SHG) microscopy, we show that collagen-fiber orientation can be viewed pseudovector fields. Subsequently, analyze them using fluid mechanic metrics, such energy U, enstrophy E, tortuosity τ....
