Three-Point Bending

A Three-Point Bend test is performed on a round rod as shown in Figure 1. As a downward force (F) is applied in the middle of the rod, the flex (Δx) is recorded. The ratio (F/Δx) is the effective stiffness of the length of rod being tested. The distance between the anvils is varied, and the resulting effect on the stiffness of the beam is measured. A graph of the resulting data yields the Flexural Elastic Modulus for the material.
