Parameteric sweep for L = 100 …. 500 mm with DL = 20mm, w = 10mm, t =1mm, Material Aluminium, MESH finer, compressive load – 1N in direction of L
Calculate analytical buckling force for this column and compare to COMSOL. Plot force F versus (t/L)2. Check that you get a linear graph. The slope is related to Modulus of the material.
Calculate for all length the relative error of the FEA as compared to Euler’s analytic solution. Err = 1 – FFEA/FEULER
