CORRECTED 2D-THEORIES FOR COMPOSITE PLATES

The objective of the paper is to propose a simple method of formulatio n of 2D-theories for composite thin plates made of an arbitrary inhomo geneous linear-elastic material. The effect of inhomogeneity on the pl ate stiffness will be described by means of extra unknowns, called cor rectors, which have to satisfy a system of linear algebraic equations. The elimination of correctors can be performed in explicit form and l eads to the formulas for effective stiffnesses of the plates under con sideration.
