This should be quick.
I was running a linear buckling analysis on a 25 x 1 x 0.5 inch Fixed-Free Column. The compressive stress distribution was established by subjecting the column to a 1.0 lbf compressive load at the free end and the results transferred into the buckling analysis. The load multiplier output value I obtained was 1196.8 and 4776.7 for Mode 1 and Mode 2 respectively. I did a hand-calculation using the Euler Column Formula for the particular end conditions and obtained a critical load of 4766.787 lbf which closely matches the value for Mode 2. So what is the significance of the mode 1 value? Why does ANSYS return this value? If such a column is ever designed, what load would it buckle at, in the real world ? I am just trying to wrap my head around this correlation.
