This work describes the effect of the stacking sequence over the distribution of the deformation and stress fields through the thickness of the laminate. The laminates are made of epoxy resin and glass fibres, having the ratio of 0 to 90° plies equal to 1. This stacking sequence is applied to obtain composite laminates with different thicknesses. The study presented in this paper is focused on the linear static behaviour of the cross/ply laminates by means of finite-element models developed using the commercial codes ANSYS 6.1 and LUSAS 15.3. The numerical models represent three-point bending loading cases. A viscoelastic analysis of the laminates based on the correspondence principle is also performed. The results from the finite element models show good agreement with those obtained using the Classical Laminate theory, while the viscoelastic storage modulus and loss factors distribution indicate the best stacking sequences for structural dynamics applications, such as spring leaves for novel car suspension systems.
