A RECIPROCITY THEOREM FOR BUCKLING STATES OF VAT (STEERED FIBER) COMPOSITE PLATES

Abstract

In the present paper the flat composite plates in buckling are studied. The plates have a symmetric lay-up and loaded along their piecewise-smooth contour by the in-plane forces. The consideration employs the Classical Lamination Plate Theory. A reciprocity theorem for the buckling states of the plate is derived and analyzed. The theorem may be used as a benchmark for the structural analysis and the optimization software.
