Hi!
I read several publications about stress relaxation of welded steel structures.
It's clear that stress relaxation happens at the first load cycles.
My curiosity concern the palstic deformations that's are local.
But these local deformations could lead a "little" permanent deformations of...
Maybe I didn't explain correctly
I'm speacking of structural steel with hgh toughness and about "local plastic deformation" due to the sum of residual stresses of welding process and stresses imposed by the load

Thanks for the answers! The problem is that is not disponible a manipulator and due to low number of shafts is economically not convenient build a manipulator or dedicated lifting device. I attach a picture of the lifting assembly to explain better the situation. The shaft will have a rim on the...
Hi!
I'm a mechanical engineer of "Below the Hook" liftng devices. I'm from Italy and this is my first thread on eng tips. I hope that my English will be comprensible.
I have a particular situation because a shaft (6,2t) must be placed into a furnace for heating until 865°C. After the heating...
