Unformatted text preview: with wave length of the order of the side dimension, a . Whether the local or the global buckling mode will occur depends on the geometry of the beam, i.e. on the dimensions L, a and t . Figure 1: Geometry and loading condition 2 1. In a Cartesian plane with the ratio (t/a) on the xaxis and the ratio (a/L) on the yaxis, draw the curve that separates the regions where the local and the global modes are active (see figure). 2. Using ABAQUS, probe the accuracy of your curve, by tracing the transition between global and local modes (see figure). Figure 2: Buckling map for the square section beam of figure 1....
