The 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...

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 کاملPlasticity Effect on Residual Stresses Measurement Using Contour Method
Residual stresses have become an important player in the field of the structural integrity for many years. Having an exact knowledge of residual stress distributions can be essential in designing the engineering components as unexpected failures are inevitable where such stresses are ignored. There are many residual stresses measurement techniques including destructive and non-destructive ones...
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...
متن کاملNumerical Analysis of explosion effects on the redistribution of residual stresses in the underwater welded pipe
Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...
