MS Plate Buckling
Computes margin of safety of a metallic plate under buckling load (generic formula)
The formula is MS = Allowable / Stress - 1
where:
'Allowable' is the compressive buckling stress allowable
'Stress' is the stress
'MS' is the margin of safety
Allowable = eta * PI^2*k*E/(12*(1-nu^2)) * (t/b)^2
where
'k' is the buckling coefficient
'E' is the Young modulus
'nu' is the elastic Poisson coefficient
't' is the panel thickness
'b' is the panel dimension
'eta' is the plasticity reduction factor: SigmaAllowablePlastic = eta*SigmaAllowableElastic
Input
E Young modulus
nu Elastic Poisson coefficient
b Panel dimension
t Panel thickness
k Buckling coefficient
eta Plasticity reduction factor
nblc Number of load cases
sigma Stress coming from load extraction
Output
MS Margin of safety
Return
