principal-stress axes Three mutually perpendicular axes (designated, σ1, σ2, and σ3) which are parallel to the directions of maximum, intermediate, and least principal stress. Their separate lengths and directions describe the state of stress at a particular point. The stress ellipse contains σ1, and σ3; the stress ellipsoid contains all three axes.
