1 Μαρ 2021 · The elastic modulus is calculated by the slope or the linear regression of the engineering stress or true stress-strain curves at a given strain range. The SB and EB are considered as the maximum engineering or true stress and strain values before failure, respectively.
Hookean materials Materials that demonstrate a linear stress–strain relationship (also called linear-elastic), therefore obeying Hooke’s law. Young’s modulus Slope of the stress–strain diagram from the origin to any point. For linear-elastic materials it is constant. Also called the constant of proportionality or modulus of elasticity.
To investigate the viscoelasticity of arteries in detail, the dynamic elastic modulus E dyn and the loss elastic modulus ηω need to be calculated considering phase lag Δϕ between diameter and pressure waveform as follows:
21 Ιουν 2024 · Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function; Compare and contrast the three types of capillaries on the basis of structure, location, and function; Describe the basic structure of a capillary bed, from the supplying metarteriole to the venule into which it drains
26 Δεκ 2019 · Figure 1. Top, the typical nonlinear relation between luminal pressure and area in large elastic arteries, explained by the progressive shift in load bearing from elastin to collagen fibers. Data translate into distensibility and pulse wave velocity (PWV) with the use of the Bramwell-Hill relation.
In elastic arteries, the smooth muscles cells are arranged in medial lamellar units which are concentric layers separated by fenestrated elastic laminae, see Figure 2. Up to 60 of these...
19 Μαΐ 2003 · The ability to characterize and quantify the elastic behavior of arteries has become increasingly important, because its application has broadened from basic physiology to clinical domains and the prediction of cardiovascular risk.
