The pressure vessel has an inner radius of R = 0.5 m and a wall thickness of t = 0.05 m. An internal pressure of 100 MPa is applied. Theoretical Solution For pressure vessels with R/t>20, thin walled theory gives side wall stresses: MPa t pR MPa t pR MPa t pR VM zz rr 118 , 1 2 5 500 2 1000 = = = and end cap stresses MPa t pR VM rr 707 2 = z z r 1 m R = 0.5 m __________________________________________________________________________ Copyright 2008 D.
