An inverse method to obtain the coefficients of bending stiffness of orthotropic composite plates by boundary displacement measurement is presented. A least square iterative scheme is given. The effect on the numerical solution caused by the changes of the model used in analysis is discussed in detail as well as the convergence of the numerical scheme and the calculation scheme of the sensitivity coefficients. The results of application show that the inverse method presented here is practical and efficient.
