In the following description about the influence of residual stress on the stability bearing capacity of axial compression member, which one is correct? ( )
A. The existence of residual stress results in parts of the cross-section of the member stepping into the plastic state before the global buckling occurring and reduces the stable bearing capacity of the axial compression member.
B. The influences of residual stress on the stability about the strong axis and weak axis are the same.
C. The distribution of residual stress has no effect on the stability of compression member.
D. None is correct.
