In the previous papers, at first, the relationship between the stress rate and the tangent stiffness with the special orthogonal group SO (3) for finite element formulation was shown. The stress rates used were Truesdell stress rate, Jaumann stress rate, Neo-Green stress rate and Ishihara stress rate. Next, tangent stiffnesses of beam elements using those stress rates were led. Next, 6 kinds of euler-buckling equations were led by 2 kinds of rotation and with or without shear deformation and axial stretch. And, euler-buckling equations of a beam by those 4 kinds of stress rates were led in order to get the guideline of finite element formulation. Then, in this paper, euler-buckling and torsion-buckling problems of those beam elements will be solved and the euler-buckling loads of those beam elements will be compared with the loads of theoritical solutions.
