In a flexing beam, the point where there is a moment of zero bending, then it is known as the point of contraflexure. At the point of contraflexure, the bending direction changes its sign to negative from positive and vice versa. For this, it needs to pass through zero and that is the point of contraflexure.
In a moment of bending diagram, it is the position at which zero line gets intersect with the bending moment curve. In real-life situations, it is very difficult to identify the exact point of contraflexure.
