Geometric Nonlinear Vibration Analysis of Heated Laminated

Abstract

Geometrically nonlinear free vibration behaviour of laminated composite cylindrical panel in thermal environment is analysed. The mid-plane kinematics is based on the higher order shear deformation theory and the geometric nonlinearity is introduced in the strain displacement relation using Green-Lagrange type nonlinearity. The sets of governing equations are obtained using Hamilton’s principle and discretised using a nonlinear finite element approach. The results obtained using the proposed model is compared with those available in open literature.
