Revision Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients
The purpose of this paper is to examine the eeects of residual stresses and strains in the oscillating arteries on the stress distribution in the vascular wall. We employ a static theory of large elastic deformations for orthotropic material (Chuong and Fung, 1986) with the acceleration term added to make the theory dynamic. We use the static elastic parameters of residual stresses in our analy...
متن کاملAnisotropic residual stresses in partially crystallized Li2O±2SiO2 glass-ceramics
Levels of residual stresses in partially crystallized Li2O±2SiO2 glass-ceramics were calculated for several crystallographic planes. The stresses were also determined by an X-ray diraction method (XRD) using synchrotron radiation. The linear thermal expansion coecient (ahkl) of a fully crystallized, stress-free, powdered sample, was measured in situ using a hot-stage XRD technique. The therma...
متن کاملThe Effect of Residual Stresses on Wave Speed in Arteries
The traditional approach to calculating stress distribution in arteries has been to assume (incorrectly) that the unloaded intact artery is stress-free. We consider the unloaded intact artery to have initial (i.e., residual) stresses and study how this aaects the calculated wave speed of the arterial pulse. We use a set of equations that describe, in a simpliied way, the blood ow in arteries an...
متن کاملStresses in Anisotropic Cylinders
Axisymmetrical stresses in an infinitely long hollow isotropic circular cylinder (plane strain) quickly approach their asymptotic values as the external radius increases. This is not the case if the cylinder is even slightly anisotropic -asymptotic solutions (for an infinitely large external radius) do not exist. We find the mechanical meaning of this disparity by using formulas for radial and ...
متن کاملResidual Stresses Measurement in Hollow Samples Using Contour Method
Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or significant decline in their service life. Therefore, it is crucial to measure the residual stresses. Contour method is a destructive testing method c...
