Hi,
Is it a good idea to drill a hole in a shaft subjected to rotating bending fatigue load? Just kidding. However transverse holes in shaft (radially drilled holes) exist and need to be assessed in view of fatigue strength.
My question is about blind holes. Hence holes with a limited depth...
Hi
I am verifying the strength of a thin-walled cylinder that is subjected to hydraulic pressure. The design is not strictly ruled by the pressure vessel code. However since there is no other applicable code Annex C “Design by analysis - Method based on stress categories” of EN 13445 is applied...
Hi, I am designing a hydraulic cylinder to comply with European pressure vessel code EN 13445.
The sealing casing will if possible be of copper-aluminium alloy EN1982 CC333G. The seal and casing is subjected to the internal pressure.
I can not find CC333G or any other copper-aluminium alloy in...
Hi, I intend to verify a component, including a bolt joint, according to EN 13445-3 Annex C. My concern is how to show that the bolt joint fulfill the requirements according to EN 13445-3 Annex C.
I am familiar with traditional bolt joint calculations for example according to VDI2230. The bolt...
Hi,
I am studying EN 13445 Annex C: Design by analysis - Method based on stress categories.
Regarding primary local membrane stress (PL): ”At discontinuities, primary membrane stresses in shells are classified as local if the equivalent membrane stress exceeds 1,1 times the nominal design...
