Problem : Pressure vessel made of alloy steel with Yield Strength of 250 MPa, Pressure acting on Pressure Vessel = 10 Atmosphere. Longitudinal Stress (σL) = 200 MPa. Hoop Stress (σθ) = 150 MPa. Radial Stress (σR) = -50. Question : a) How thick is the pressure vessel if the Inner Diameter is D = 2 Meters? b) Check whether the pressure vessel is safe or not? c) Check whether the pressure vessel is safe or not with Tresca yield criterion and compare it with von Mises yield criterion?

c) Check whether the pressure vessel is safe or not with Tresca yield criterion and compare it with von Mises yield criterion?
Given data: -
The yield strength of the pressure vessel is σy = 250 MPa.
The inner diameter of the vessel is d = 2 m.
The pressure acting in the vessel is P = 10 Atm.
The longitudinal Stress is σL = 200 MPa.
Hoop Stress σθ = 150 MPa
The Radial Stress is σR = -50 MPa.
