“…determination of critical load for a known material property and geometry, is still a challenging one. Yet, there are valuable contributions in the modern literature, such as the ones by Ruta et al [17,18], based on a onedimensional model for thin-walled beams [19], which provides exact solution to critical loads in closed-form, by Gupta et al [20] for post-buckling behavior of laminated beams, Mercan and Civalek [21] for critical load of nanobeams, and Abbondanza et al [22] for vibration frequencies and buckling loads of nanobeams. In addition, there are numerous studies which focus on numerical solutions of such problems, which ensures required accuracy for engineering applications when tackled the numerical problems, such as locking, but lack generality as they require the numerical values of the parameters of the problem.…”
