| Abstract: | A two dimensional elastic foundation to analyze the buckling of composite sandwich plates containing delamination between two faceplate laminates is established. By employing Rayleigh Ritz method, this paper studies the hygrothermal effect on buckling character of composite sandwich plates containing delamination between two faceplate laminates. The elastic coefficients and the hygrothermal coefficients of the composite faceplate laminate are dependent on temperature. |

| Keywords: | hygrothermal effect delamination buckling composite sandwich |
