摘要：

This work presents a new laminated composite beam model based on discrete layer theory, the model is applied in statics and in dynamics on thin and thick beams. It allows one to satisfy automatically the continuity 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 cosine function (Ossadzow, Muller and Touratier) contrary to the different models existing in the bibliography. The motion equations and the natural boundary conditions result from the virtual power principal. In order to validate the proposed model, several problems in bending, buckling and free vibration are presented. (C) 1998 Elsevier Science Limited. All rights reserved.
