ASTM D is a test method for the determinations of flexural properties for unreinforced and reinforced plastics. These materials include high-modulus composites and electrical insulating materials. This flexure test requires a 4 point fixture where the bottom span is set by the span-to-depth of Two test procedures, Procedure A and B are used depending on the material properties.

Procedure A is used for brittle materials that break at low deflections. Procedure B is used for flexible, more ductile materials that undergo large deflections.

It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

Suitable for both dynamic and static testing, the 3-Point Bend Fixture easily provides the capability of a 3-point flexure test. The asstm is supported on two lower anvils and the load is applied in the center of the specimen by a single upper anvil. The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available.

The AutoX is a high-resolution, long-travel automatic contacting extensometer. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. The series of extensometers offers speed of attachment and ease-of-use.

The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension. The low operating-force arms of the extensometer reduce the possibility of knife-edge slippage when testing hard or smooth surfaced materials.

The challenges of testing to this standard are: Flexural strain measurement Repeatability of calculations Reporting calculations in compliance with the standard Instron Solution: Flexural strain measurement — ASTM D requires that the method used to measure strain is not influenced by the compliance of the machine.

Advanced strain solutions include non-contacting extensometers, such as the Advanced Video Extensometer AVE 2 and automatic contacting extensometers, such as the AutoX These solutions require little influence from the operator, resulting in improved repeatability.

Clip-on extensometers such as or attached to a deflectometer plunger also meet Class C deflection measuring requirements. Repeatability of calculations — When setting up the test, having an adequate preload is highly recommended to ensure accurate and consistent strain measurements.

Flexural Properties by Four-Point Bending ASTM D

The amount of force applied to the specimen prior to starting the test directly impacts the repeatability of calculations, such as flexural modulus. Alternatively, slack correction can be used to ensure that the calculations are performed on the appropriate section of the testing data.
