Based on the two-dimensional elasticity theory, the buckling modes of delaminated composite beams are studied in this paper. Firstly, critical buckling loads are obtained. Then, the displacement modes of the beam are given by substituting the critical loads back to the eigenvalue equations. The possible contact between the delaminated interfaces is considered, and “Free” and “contact” modes are separately computed. According to the situations of the vertical displacements and normal stresses on the delaminated interfaces, the real buckling modes can be judged.
