Abstract
A finite difference numerical solution for the thermoelastoplastic performance of rotating multilayer (sandwich) cylinders is presented while considering the materials' properties temperature dependency. Each layer is treated as a composite with volume fractions being constant, independent on the position, and unique. The cylinder is rotating with a variable (exponential) angular speed leading to the presence of shear stress. Regarding plasticity analysis, von Mises failure criterion is considered while the constituent materials have a nonlinear strain hardening. Different case studies are examined and discussed. Results revealed that the layers' arrangement and the maximum temperature position substantially influence the cylinder's performance. Additionally, cylinders with smaller size are able to sustain the prescribed loads compared to larger ones.
