Everyone, how is the strength of a hemispherical and cylindrical head checked?
Thread Content
Today, I received a device with round tops and square bottoms, operating at a pressure of 0.002 MPa. How should the strength of such round-top and square-bottomed covers be calculated for stress verification? In what other situations would equipment use hemispherical end caps?
If it has to be calculated, finite element analysis is likely required
A 200mm high water column is sufficient for verification.
The pressure is 0.002 MPA; the load resulting from this pressure can be ignored. It is sufficient to consider the stiffness instead
This pressure is essentially at atmospheric pressure; the stiffness is calculated based on a fully filled condition

Teacher, I have a gentle question: how is stiffness calculated?

For very large structures, such as the circular-shaped smoke and air ducts in steel plants, the thickness calculated using these empirical values would be too large; in actual engineering practice, thin plates along with external reinforcement bars and internal supports are used. Do you have specific dimensions?
