A Two-Dimensional Model of Hypertension-Induced Arterial Remodeling With Account for Stress Interaction Between Elastin and Collagen
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a novel structure-based two-dimensional (2D) mathematical model of hypertension-induced arterial remodeling. The model is built in the framework of the constrained mixture theory and global growth approach, ...
A Preliminary Analysis of the Data From an in Vitro Inflation Extension Test Can Validate the Assumption of Arterial Tissue Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study is to propose a method for preliminary processing of the experimental data from an inflationextension test on tubular arterial specimens. The method is based on the condition for existence of a ...
A Mathematical Model of Maladaptive Inward Eutrophic Remodeling of Muscular Arteries in Hypertension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a relatively simple two-dimensional mathematical model for maladaptive inward remodeling of resistive arteries in hypertension in terms of vascular solid mechanics. The main premises are: (i) maladaptive inward ...
Are Geometrical and Structural Variations Along the Length of the Aorta Governed by a Principle of “Optimal Mechanical Operation�
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is welldocumented that the geometrical dimensions, the longitudinal stretch ratio in situ, certain structural mechanical descriptors such as compliance and pressurediameter moduli, as well as the mass fractions of ...
Image-Based Estimation of Left Ventricular Myocardial Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elevation in left ventricular (LV) myocardial stiffness is a key remodeling-mediated change that underlies the development and progression of heart failure (HF). Despite the potential diagnostic value of quantifying this ...
Contractile Smooth Muscle and Active Stress Generation in Porcine Common Carotids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical response of intact blood vessels to applied loads can be delineated into passive and active components using an isometric decomposition approach. Whereas the passive response is due predominantly to the ...
