With the discovery of Tsai‘s Modulus as a fundamental property of composite material and the newly introduced double-double laminate family (DD), new and highly efficient methods for the design of composite laminates are available. Two novel approaches are proposed for the invariant-based analysis of stability and displacement of simply supported double-double type composite panels. These methods are shown to accurately predict the field of displacement and the buckling load for double-double type laminates independent of material and laminate thickness. Both methods combine known solutions based on the classical laminate theory with new approaches of the invariant-based theory of composites presented by Tsai and Melo (2014).

Abstract

With the discovery of Tsai‘s Modulus as a fundamental property of composite material and the newly introduced double-double laminate family (DD), new and highly efficient methods for the design of composite laminates are available. Two novel approaches are proposed for the invariant-based analysis of stability and displacement of simply supported double-double type composite panels. These methods are shown to accurately predict the field of displacement and the buckling load for double-double type laminates independent of material and laminate thickness. Both methods combine known solutions based on the classical laminate theory with new approaches of the invariant-based theory of composites presented by Tsai and Melo (2014).
