Good morning/evening everybody !
My main goal is to have the critical buckling load on a composite airfoil on ANSYS APDL.
To be sure I understand the methodology, I used a simple case : a beam with a cross section of 10mm (H=B=10mm) and a height of 100mm (L=100mm) with a Young modulus of 2e9 and a Poisson ration of 0.3 and an axial load that will "provide" the buckling.
According to the theory, Pcr= (E*L*pi^2)/(4*L^2) for n=1 so my critical buckling load will be 4.11233e11 N.
How, on ANSYS APDL, can I have access to this value (calculate by the computer) ? And the values for the other modes ?
Thanks in advance !!
I will join my case commands lines attached here.
