Finite element analysis of rectangular composite plates subjected to a uniformly distributed load

Most structures are subjected to severe static and dynamic stress, as well as a variety of constrained situations, during their service lives. As a result, the structure may flex, buckle, or vibrate. Precise forecasting of the static and vibration responses of laminated composite /skew plates with l...
