Development, model validation, and preliminary experimental verification of an FEA program for structural analysis of casing in casing for oil wells.
… gas wells rely upon long steel pipes, known as casing, that run down the depth of the well. During drilling, a section of pipe is cemented in place and another section of casing is run inside, repeating this process as necessary. This process is not 100% accurate, leading to eccentric …

Mechanical behavior of shell casing and separator of lithium-ion battery
… consist of cathode, anode, separator and shell casing or aluminum plastic cover. Among them, the shell casing provides substantial strength and fracture resistance under mechanical loading, and the failure of the separator determines onset of internal short circuit of the cell. In the first part …
