Thermal and thermomechanical buckling of CNT-reinforced composite sandwich cylindrical shells including elasticity of tangential edge restraint

This paper presents an analytical approach to investigate the buckling of sandwich cylindrical shells subjected uniform temperature rise and external lateral pressure. Two models corresponding carbon nanotube reinforced composite (CNTRC) face sheets core layer are considered. The properties all constitutive materials assumed be dependent effective CNTRC determined according extended rule mixture. Governing equations established using first order shear deformation theory solved employing two-term form deflection along with Galerkin method for simply supported edge shells. In account practical situations in-plane boundary condition, elasticity tangential constraint edges is included. Owing dependence material properties, critical thermal loads adopting iteration process. Numerous parametric studies carried out interesting remarks given. study reveals that shell model homogeneous skins has considerably strong capacity resistance. Numerical results also indicate significant effects on loads, especially at elevated temperature. addition, in case load, intermediate volume percentage nanotubes can confer highest temperatures
