Below is the simulation for the bi-laterally constrained column. Here line-contact was solved for analytically, and is highlighted in red. This system goes through the same modal sequence 1-2-3. It can be seen that the system spends more time in line-contact than in point-contact and pre-contact combined. This would suggest that for systems that often buckle into mode sequence 1-2-3, that a safe place to put a joint in the constraint would be at the L/2. …show more content…
This sequence more commonly occurs on longer systems. The 12in3w simulation is depicted below (Figure 5.13). Similarly, the load-displacement is labeled where the corresponding shape snapshots were taken. Figure 5.14 12in3w load-displacement showing 1.5-2.5-3.5 modal
