Abstract
Abstract The present work addresses the changes occurring in buckling strength and natural frequency of a conical panel with thermal loads using finite element methods. First, the critical temperature of the conical panel at which the buckling occurs is computed, followed with pre-stressed modal analysis. The influence of different geometrical dimensions and boundary constraints on the buckling strength and natural frequencies with its corresponding mode shapes of the panel is investigated. It reveals that the geometrical parameters significantly affect the buckling strength of the panel. Further, natural frequencies drastically drop at a temperature close to buckling temperature. Other important observations are also presented and discussed.
