A new simple method for shell vibration analysis with initial stress accounting

Stability of feeding cylinder shell under torsion in pneumo-mechanical spinning machines

“…Mechanical compact spinning is an important alternative for compact yarn production. The system is cheaper and less complicated than pneumatic compact yarn spinning systems [10]. At critical values of these forces, qkp, the shell loses stability with a violation of the circular shape of the section.…”

“…They obtained vibration modes and frequencies of the hyper-elastic membrane by analytical and numerical methods and then reduced the order of the models for noncolinear dynamic analysis, which was achieved by the Galerkin method. They used the finite element model to check the accuracy of the reduced order model [10].…”

“…Cylindrical shells are the most studied type of shell and their behavior describes many theories and solutions [10]. In recent decades, a number of research studies have been carried out around laminated cylindrical shell structures, which are fully recorded in the literature [11].…”
