Abstract The elastic properties of a thermally sprayed coating were determined by a three-point bending (3PB) test and nanoindentation, but different results were obtained by the two methods.
In three-point bending the maximum bending moment is attained at the point where the force is applied, and decreases as distance from this point increases.
