Unveiling Transient to Steady Effects in Reduced Order Models of Thermomechanical Plates via Global Dynamics

摘要

A reduced model of third-order shear deformable plate with cubic temperature is used to investigate the system nonlinear dynamic response in a full thermomechanical coupling framework. Numerical investigations of local and global dynamics allow to highlight distinct response features as occurring under different (constant or dome-shaped) prescribed spatial temperatures on the plate surfaces. In both cases, the important role played by global analysis for unveiling meaningful transient to steady effects in the system dynamics clearly comes out.
