	Symmetrical laminates do not exhibit a tendency to twist as a result of the cooling phase during fabrication. For these reasons, symmetrical composites are widely used by designers in engineering practice. These materials are better “tailored” to the demands of optimal designs. In general, designers evade non-symmetric sequences of layers in this type of structures. Given a wide range of application possibilities for non-symmetric and general laminates, it is worth focusing on their advantages. Such laminates are very interesting in terms of passive structures, where in-plan load induces out-of-plane deformation. In order to solve this problem, it is necessary to describe the behaviour of thin-walled structures made of general laminates under any loads. The main disadvantage of general laminates is connected with mechanical couplings. There are many types of couplings which depend on the stacking sequence of laminate layers. The presence of mechanical couplings causes that their mechanical properties will be changed both in buckling and post-buckling states. In the literature one can find few studies on the effect of non-symmetrical couplings on the behaviour of composite structures under compression.
