The present paper shows an identification method of bending stiffnesses of symmetrically laminated plates using bending deflections under static loading. Firstly, three bending stiffnesses of simply-supported orthotropic plates are identified by using an analytical expression. Secondly, four or six bending stiffnesses of symmetrically laminated plates are identified by using the finite element method and the nonlinear optimization technique. Effects of the number of measured deflections on the identified bending stiffnesses are examined numerically.
