The point of inflection is BM is 0.
The point of contraflexure is BM is 0 and change its sign.
That is all point of contraflexures are the point of infletion but all point of infletion are not point of contraflexure.
Hope you understand.

Point of Contraflexure is point on bending moment diagram and point of inflection is point on the deflected shape.
POC is the point where bending moment changes sign and POI is the point where curve changes sign (EXP- convex to concave).

Contraflexture means opposite bending means conraflexture is which point these bending is zero there don't any typical bending created its than possible that all these signs of these beam are opposite and beam edge are long.

The Point of inflextion is used in case of the elastic curve. Where the curve changes from concave to convex (or) convex to concave.
The contraflexture used in case of B.M.D where the B.M change its sign.

Contraflexure means the point where BM changes sign or becomes 0.
Inflection means the point in the beam where the deflected shape changes, either from hogging to sagging or saaging to hogging.

Generally, Point of cocontra flexure Point of inflexion these are same, inflexion is the word of math which means curve change own sign and contraflexure is the word from Mechanics.

In which beams con-traflexture points occur?
I need maximum number of con-traflexture points for cantilever, simply supported, propped, overhanging and fixed beams.

Note not to confuse between point of contraflexure and point of inflection. Many saying they are same but they are not actually same, they both are different.

POI are the points where bending moment equals zero.
POC are the points where bending moment changes the sign.
So, all POC are POI, but all POI are not POC.

Inflection point ----- it is the point, where S.F is 0 or change its sign.
Contraflexure point ----it is the point, where B.M is 0 or change its sign.
Contraflexure point ----it is the point, where B.M is 0 or change its sign.
