Lame's equation for thick walled cylinder
Webb23 mars 2024 · ε θ = σ θ − ν ( σ r + σ z) E u = ε θ r While I’m satisfied this is correct, I don’t understand why. Why doesn’t the radial deformation result from the radial strain as I expect it should, according to ε r = σ r − ν ( σ θ + σ z) E u = ε r r What I've tried so far Webbii. Radial stress is a direct result of the fluid pressing against the cylinder walls. Its effect is to reduce the thickness of the cylinder. iii. and the longitudinal stress results from the change in length of cylinder. Lame’s equations; Consider a thick cylinder of internal radius R 1 and outer radius R 2 , subjected to internal pressure,

THIN WALLED CYLINDER. A cylinder is regarded as thin walled when the wall thickness t is less than 1/20 of the diameter D. When the wall is thicker than this, it is regarded as a thick wall and it is treated differently as described later. Consider a cylinder of mean diameter D, wall thickness t and length L. When the pressure inside is
