Abstract
Refined higher-order displacement models for the behaviour of symmetric and unsymmetric laminated composite beams based on C0 finite element discretization are presented. These theories incorporate a more realistic non-linear variation of longitudinal displacements through the beam thickness, thus eliminating the use of shear correction coefficient(s). The discrete element considered is a four-noded cubic with kinematic models having three, four and five degrees of freedom per node. The computer program developed incorporates the realistic prediction of interlaminar stresses from equilibrium equations. The present results, when compared with the elasticity solutions, show excellent agreement. In addition numerical results for sandwich beams are presented for future reference.
