Stress in pressurized sphere
WebThis page includes the determination of stresses and strains resulting from pressurization of a thick-walled spherical vessel whose wall is comprised of a Hookean material, one that has a linear stress-strain relationship. What does this have to do with a heart? Well, more than the "Law of LaPlace" so often cited in cardiology texts. WebA more general approach at finding the Tensile Stress σ is by cutting the sphere into two hemispheres [10,11] as shown in Figure 2 which can be used to show that í µí¼ = í µí± í µí± …

This paper presents an analytical procedure for estimation of the radial and circumferential stresses in spherical pressure vessels under …
WebTheoretically, a sphere would be the best shape of a pressure vessel. Unhappily, a spherical shape is tough to manufacture, therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end. Smaller pressure vessels are assembled from a pipe and two covers. Web8.4.1.1 Thick Cylindrical Pressure Vessels Under Internal Pressure Only. If p o = 0, Equations (8-35) and (8-36) reduce to. F r = a 2 p i b 2 − a 2 ( 1 − b 2 r 2) (8-38) and. F t = a 2 p i b 2 − a 2 ( 1 + b 2 r 2) (8-39) Both of these stresses have maximum magnitudes at r = a. If the maximum shear stress theory of failure is to be used ...
