Question

A spherical pressure tank is made of 1050 cold-drawn steel (Sy = 84 ksi, Su = 100 ksi). The tank has a 40" inner diameter, has a 1/2" wall thickness, and is pressurized cyclically between 200 psi and 1000 psi. Using the Goodman fatigue criterion for infinite life, find the overall safety factor against fatigue failure.

Step 1

In this case, the pressure is cycled between 200 psi and 1000 psi, so the mean stress is: σm = (200 + 1000) / 2 = 600 psi Show more…
