The first case is a trivial case, it corresponds to no deflection, and therefore no buckling - it describes the case when the axially applied load simply compresses the beam in the x direction. Plate Deflection and Stress. The hole is positioned at point 0. A summary of the parameters used is given in the Matlab Command Window: wavelength [m] = 6.
