are thick walled stress equations more accurate than the thin walled stress equations for both the thin and thick walled pressure vessels
Added by Deanna W.
Step 1
This is an approximation valid when t ≪ r_i (often t/r_i < ~0.1). - Thick-walled (Lame) stress: uses the exact solution for a thick-walled cylinder under internal (and/or external) pressure. The radial and hoop stresses vary with radius r inside the wall and are Show more…
