Abstract:An inverse method was proposed for the identification of the stiffness coefficients of laminated composite plates. The weighted least square iterative computational equations were given and differential instead of partial derivative was used to compute sensitivity coefficients. The convergences expressed by the iterative computations were discussed, and inverse computation was carried out for 3 laminated composite plates.
Key words: inverse analysis composite laminated plate stiffness coefficient
