Why Bend Testing?Bending test Tensile stress is generated on the convex surface of the specimen and compressive stress is generated on the concave surface. This creates an area of ​​shear stress along the midline. To ensure that the primary failure is from tensile or compressive stress, shear stress must be minimized.

Why perform a bend test?

Bend test Measure the force required to bend a beam of plastic material and determine the bending resistance or stiffness of the material. Flexural modulus indicates how much a material can bend before it is permanently deformed.

Why is flexural strength important?

High flexural strength is Pressure repair is essential, when high pressure/stress is applied to the material or restoration. Therefore, the flexural strength also determines the indications of the material.

How to perform a bend test?

Bend tests are more affordable than tensile tests, and the test results are slightly different.This Material is placed horizontally on two contact points (lower support span) A force is then applied to the top of the material through one or two contact points (upper loading span) until the sample fails.

Why do we use the three-point bend test?

The three-point bending test (Figure 1) is a classic experiment in mechanics, used for Measuring Young’s Modulus of Beam-Shaped Materials. A beam of length L rests on two roller supports and bears a concentrated load P in its center.
