Bending of cross-ply laminated clamped plates using lagrange multipliers

Bending and Forced Vibration Response of a Clamped Orthotropic Thick Plate and Sandwich Panel

“…Chandrashekhara et al [13] adopted the Lagrangian multiplier technique for the bending analysis of cross-ply clamped laminates while Ramkumar et al [9] and Chen and Ramkumar [10] used it to predict the dynamic response of clamped orthotropic plates including transverse shear. In these approaches, the displacements of the plate are assumed as…”

“…A four-layered cross-ply [0/90/90/03] graphite/epoxy laminate studied by Chandrashekhara et al [13] has the following material properties: E "21;10 psi, E "1)4;10 psi, G "G "0)6;10 psi, G "0)5;10 psi and…”

“…The results are in excellent agreement for all b/a ratios. Only the de#ection data is available from Chandrashekhara et al [13]. All the computed bending moments were derived from the proposed approach and LMT described in this paper.…”
