"We are at the bottom headed for the next double dip, in my view".
FEA models, including both contact and geometry imperfections, were used to investigate the buckling pressure of the bottom head.
In this paper, the buckling behavior of the bottom head was studied by experimental and finite element analysis (FEA) methods.
The bottom head in the residential electric water heater tank is an externally-pressurized, thin-walled, torispherical structure.
The results also show that the contact between the bottom head and the shell has a reinforcing effect on the buckling strength of the head.
In the method, the cask and the new fuel are not considered individually, and the mass of the new fuel elements is averagely allocated to the bottom head of the cask.
To evaluate the tube ejection mechanism, temperature distributions of the reactor bottom head and in-core instrumentation penetration were measured by a series of thermocouples embedded along the specimen.
This study proposes an experimental analysis of the creep, crack initiation and crack propagation phases in a 16MnNiMo5 steel subjected to thermomechanical loading representing a core meltdown accident in a pressurized water reactor involving the transfer of a molten corium bath to the bottom head.
Orcas lunged at trainers, pulled them in the water, held them at the bottom, head-butted them, slammed them with tail flukes and breached on top of them.
Following the failure of a large cylindrical fluid coker with a shallow spherical bottom head while undergoing its hydrostatic proof test at Avon, California, in 1956, interest in the problem of buckling of such pressure vessels under internal pressure was growing.
