M. Karama et al., BENDING, BUCKLING AND FREE-VIBRATION OF LAMINATED COMPOSITE WITH A TRANSVERSE-SHEAR STRESS CONTINUITY MODEL, Composites. Part B, Engineering, 29(3), 1998, pp. 223-234
This work presents a new laminated composite beam model based on discr
ete layer theory, the model is applied in statics and in dynamics on t
hin and thick beams. It allows one to satisfy automatically the contin
uity of transverse shear stresses by taking into account the Heaviside
step function. The transverse shear is represented by a sine function
(Touratier). This model introduces membrane refinement through a cosi
ne function (Ossadzow, Muller and Touratier) contrary to the different
models existing in the bibliography. The motion equations and the nat
ural boundary conditions result from the virtual power principal. In o
rder to validate the proposed model, several problems in bending, buck
ling and free vibration are presented. (C) 1998 Elsevier Science Limit
