How to Download ASTM D3410 PDF for Free
ASTM D3410 is a standard test method for compressive properties of polymer matrix composite materials with unsupported gage section by shear loading. It is applicable to composites made from unidirectional tape, wet-tow placement, textile, short fibers, or similar product forms. It is widely used in material specifications, research and development, quality assurance, and structural design and analysis of composite materials.

ASTM D3410 is based on the principle of applying a compressive force to the specimen through shear at wedge grip interfaces. This type of force transfer differs from other methods of compressive testing, such as end-loading, combined shear and end loading, or four-point bending. The advantages of ASTM D3410 are that it can measure the in-plane compressive properties of composite materials with high-modulus fibers and that it can avoid buckling or end crushing failures that may occur in other methods. However, the disadvantages of ASTM D3410 are that it requires a special testing fixture and that it may introduce stress concentrations or shear failures at the grip interfaces.
To perform ASTM D3410, the specimen should have a rectangular cross-section with a constant width and thickness. The specimen should also have a gage section that is unsupported by the grips and has a length-to-width ratio of at least 12. The specimen should be prepared according to the material specifications and the standard procedures. The specimen should be conditioned to the desired environment before testing. The testing fixture should consist of two pairs of wedge grips that can apply a uniform compressive force to the specimen without slippage or damage. The testing machine should be capable of applying and measuring the compressive force and displacement with sufficient accuracy and resolution.
The test procedure involves inserting the specimen into the testing fixture and aligning it with the loading axis. The compressive force is then applied to the specimen at a constant rate until failure occurs. The force-displacement data is recorded throughout the test. The ultimate compressive strength is calculated as the maximum force divided by the cross-sectional area of the specimen. The ultimate compressive strain is calculated as the change in length divided by the original length of the gage section. The compressive modulus of elasticity is calculated as the slope of the initial linear portion of the stress-strain curve. The Poisson's ratio in compression is calculated as the ratio of the transverse strain to the axial strain in the elastic region. The transition strain is calculated as the strain at which the stress-strain curve deviates from linearity. aa16f39245
