Abstract
A shear-locking free robust isoparametric three-node triangular finite element is developed for advanced fiber-reinforced arbitrarily lamina ted moderately-thick and thin plates. The strain-displacement relation s are based on Reissner and Mindlin plate theory that accounts for tra nsverse shear deformations into the plate formulation. A shear correct ion term is introduced into the finite element formulation to circumve nt the shear locking effect. Numerical results, for illustration purpo ses, are presented for a simply-supported plate with cross-ply laminat ions subjected to uniform transverse loads, constituting study of conv ergence and shear locking effects on transverse displacement and momen t, and their variations for various parametric effects.
