Bending of laminated beams using

Timoshenkomodel via nonlocal elasticity

Abderrahmane Besseghier, Abdelouahed Tounsi, Adda Bedia El Abbas

Abstract : In this paper, the bending of laminated beamsusing first order shear deformation theory via nonlocal elasticityis presented. The analysis is presented for static flexure ofsymmetric and anti-symmetric cross-ply laminated beamssubjected to sinusoidal load.Governing equations and boundary conditions are obtainedby using the principle of virtual work.Analytical solutions of bending for simply supportedlaminated beams are presented using this theory to illustrate theeffect of nonlocal theory, and the influence of aspect ratio isexamined.
