Summary

The critical buckling load of a composite plate is calculated with a FEM formulation that uses a new shear deformable quadrilateral element.The effects of material anisotropy. meshsize, aspect ratio, number of laminae and the lamina orientation angles are studied. The results show that the classical plate theory is inadequate to obtain accurate results since the transverse shear stresses are not taken into account properly. The critical loads obtained in the present approach, correlate very well with those of closed form solutions and three dimensional formulations. Thus the present approach increases the computational efficiency and provides a simpler formulation.
