In this paper, skew isotropic plates subjected to in-plane loadings are analyzed using a stability analysis based on the isoparametric spline finite strip method, which includes inelasticity. Using this method, the initial inelastic local buckling of skew plates with or without intermediate line supports is studied based on Ramberg–Osgood representation of the stress–strain curve using the deformation theory of plasticity. Stiffness and stability matrices are formulated by energy expressions using the small deflection theory. The effect of tapered section on the local buckling of skew plates is taken into account. Finally, the inelastic local buckling loads of these plates are obtained and the results are compared with known solutions in the literature.
► Isoparametric finite strip method was used to study local buckling of skew plates.
► Skew plate with or without line supports was considered in this study.
► The local buckling of skew plate containing tapered sections was also investigated.
► Local buckling coefficient of skew plates is lower than that for non-skew plates.
