For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: (for a cylinder) For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: (for a cylinder) WebThin cylinders The tangential stress is uniform across the wall; so, from equilibrium of the free body : σ t = ( p i D i - p o D o) / 2 t Since D i / t > > 1, this equation with ( i), yields : ( 1) σ …
WebThe two basic equations for a thin shell of revolution are (8-1) and (8-2) In these equations, R mer is the radius of curvature of a meridian line and R is the distance from the shell to its axis of rotation along a normal to the shell. Both of these radii are taken to a surface located midway between the inside and outside surfaces of the shell. WebSep 2, 2024 · The internal pressure generates a force of pA = p(πr2) acting on the fluid, which is balanced by the force obtained by multiplying the wall stress times its area, σϕ(2πrb). Equating these: p(πr2) = σϕ(2πrb) σϕ = pr 2b Note that this is a statically determined result, with no dependence on the material properties.
