The thin-walled cylindrical pressure vessel is subjected to an internal pressure of 15 mpa. the vessel is 3m long, has an inner radius of 0.5 m, and a thickness of 10 mm. it is constructed of structural a-36 steel. compute the final diameter and the length of the pressure vessel.

Final diameter = 1.0032  m

Final length =3.0027 m

Explanation:

Given that

P= 15 MPa

r= 0.5 m

L= 3 m

t=10 mm

For  A-36 steel ,modulus of elasticity = 200 GPa

Hoop stress

Longitudinal stress

Hoop strain

Take μ=0.26

Final diameter = 1.0032  m

Longitudinal strain

So the final length = 3.0027 m
