Hai all, I am performing shear buckling analysis of plate girdersusing ansys. The ultimate shear buckling strength can be easily obtained by applying concentrated load on the model. My issue is to obtain critical shear buckling strength accurately. Some tutorials tell that critical buckling can be obtained from the load - deflection curve where large deformation is initiated.How can i track values exactly. I there any alternative method to track critical buckling.If anyone finds a solution, please reply......
