Abstract

Design and assessment of thermal stresses in multi-layered composites has always been area of major concern, as delamination/debonding of the laminae poses a serious issue in the failure of the laminate structure. Stresses at interface can be obtained more swiftly by analytical method when compared to finite element method. In the current work, a comparison has been made between finite element model and first order approximated analytical formulae derived using classical plate theory for a cantilever beam type composite laminate structure with orthotropic material properties. A three-layered structure with orthotropic material properties subjected to uniform thermal load is presented. A comparison has been made among obtained results, Ansys results and the results from similar work carried out in published journal paper. Results obtained from the present work was found to be in close comparison to the Ansys results, stating quantitatively 10.7% from the Ansys results calculated at interface-2, while qualitatively both of them follows the similar trend.
