Snap-through buckling results

Vladimir_Gantovnik

Guys, I have two snap-through buckling examples: 1) panel loaded by SPCD, 2) panel loaded by pressure. In the first example, I request SPCFORCE, and then make nice plot SPCFORCE vs Displacement for center node using HyperGraph (see the image). But I don't understand what force should I use to show span-thru in the seconds example with applied pressure. Please, help me.

Hi Vladimir,

you can request OLOAD output and use the applied forces computed from the pressure to plot the graph.

Hope this helps.
