Buckling strength predictions are presented for a wide range of thin isotropic skew plates, subject to uniform uniaxial compression. The key studied parameters include the aspect ratio, skew angle and rotational restraint stiffness on the different edges of the plate. The buckling strengths are evaluated both for isolated plates and for plates which are continuous with other parts of the structure. The buckling predictions are presented in the form of dimensionless buckling curves, which permits a ready adoption into the "data sheets" commonly used in current design.
