Journal ArticleDOI
Micromechanically-motivated analysis of fibrous tissue.
TL;DR: A micromechanical model based on structural parameters of collagen fibers that were extracted from second-harmonic generation images of the two samples is developed, which has the potential to reduce the need of time-consuming experimental data of the mechanical behavior of fibrous tissues.
Journal ArticleDOI
The Effects of Viscoelasticity on Residual Strain in Aortic Soft Tissues.
TL;DR: In this article, a structural tensor model for arterial tissues from Holzapfel and Ogden for fractional viscoelasticity was extended to capture consistent levels of hysteresis observed in biaxial experiments.
Soft Tissue Biomechanics: A necessity for future directions in engineering and medicine
TL;DR: The mechanical description and the physical modeling of arteries was found to be a general feature of arteries of the muscular type and the analytical expressions for the algorithmic stress and elasticity tensors are implemented in the FE analysis program FEAP.
Journal ArticleDOI

TL;DR: A semi-automatic method for generating conforming hexahedral meshes directly from contours segmented from medical images, which efficiently generates high-quality elements suitable for FE analysis, even in the bifurcation region of the aorta into the iliac arteries.
