The incision angle of mediolateral episiotomy before delivery and after repair

To assess the relevance of the suture angle when evaluating mediolateral episiotomy, and the safety of the accepted lower limit of 40° for the incision angle.

Fluid-Structure Interaction in Finite Element Modeling of Traumatic Aortic Rupture

Traumatic Aortic Rupture (TAR) during automobile crashes is one of the leading causes of fatality. In this study, the physical parameters and mechanisms of aortic rupture in dynamic pressure loading condition were investigated using different numerical approaches in a finite element model, including Eulerian, Arbitrary Lagrangian-Eulerian (ALE), and Smoothed Particle Hydrodynamics (SPH) formulations. The TAR models were compared against in vitro experiments and predicted the most probable location of rupture at the isthmus as indicated in the literature.Copyright

Analysis and Modeling of Aortic Tissue Material Properties

A hyperelastic material with linear viscoelasticity was used to characterize the mechanical behavior of aortic tissue based on literature and new experimental data. It was shown that the previous data led to contradictory uniaxial and biaxial responses. A set of new material properties were identified which closely described the experimental data for strains below 40%.Copyright
