- Parallel section of the test specimen. The specimens were fabricated with an abrasive waterjet cutter from sheet material. Figure 1: ASTM E8 2 rectangular tension test specimen used for uniaxial testing (nominal dimensions in mm). Mechanical testing equipment Figure 2 shows the testing machine and the location of DIC cameras and lighting.
- ASTM E8 Metal Tensile Testing. Measure and record the specimen dimensions necessary to determine the cross sectional area at its smallest point. The original cross sectional area is used for all engineering stress calculations. Use ink and a scribe or punch to place gage marks on the test specimen at the appropriate gage length.

This study specifically looks at tensile specimens because of their high use for qualifying and certifying parts produced in AM. Therefore the changes in geometry, size, and orientation are being varied within the context of the specimens outlined in the ASTM E8/E8M-16a. Materials and Methods 3.1. Titanium Powder. Astm E8 Tensile Specimen Dimensions List. Tensile Test Coupon Dimensions. The tensile test on metals or metallic materials, is mainly based on DIN EN ISO 6892-1 and ASTM E8.Both standards specify specimen shapes and their testing. The objective of the standards is to define and establish the test method in such a way, that even when different.
The forces used in determining tensile strength and yield strength shall be within the verified force application range of the testing machine as defined in Practices E4.

The distance between spherical bearings should be as great as feasible. This requires that liners of several thicknesses be available to cover the range of specimen thickness.
Proper alignment of wedge grips and liners is illustrated in Fig. Astm c astm normas fibra de vidrio.

NOTE 3—Punching or blanking of the reduced section may produce significant cold work or shear burrs, or both, along the edges which should be removed by machining. If, however, for em reason, one grip of a pair advances farther than the other as the grips tighten, an undesirable bending stress may be introduced.
The gauge length is the most significant difference between E8 and E8M test specimens. Parte 1 de 8 Designation: Both of these gripping devices should be attached axtm the heads of the testing machine through properly lubricated sphericalseated bearings. Extensometers shall be used and verified to include the strains corresponding to the yield strength and elongation at fracture if determined.
For this reason, a small w8 is permitted in the reduced section of each of the specimens described in the following sections. For measuring elongation at fracture with an appropriate extensometer, the gauge length of the extensometer shall be equal to the nominal gauge length required for the specimen being tested.

When liners are used behind the wedges, they must be of the same thickness aatm their faces must be flat and parallel. For best results, the wedges should be supported over their entire lengths by the heads of the testing machine.
Such interpretation is usually applicable to values for reduction of area reported in the literature when no further qualification is given. For short specimens and for specimens of many materials it is generally necessary to use machined test specimens and to use a special means of gripping to ensure that the specimens, when under load, shall be as nearly as possible in uniformly distributed pure axial tension see 5.
To ensure axial tensile stress within the gauge length, the axis of the adtm specimen should coincide with the center line of the heads of the testing machine.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. No further reproductions authorized. NOTE 1—The effect of this eccentric force application may be illustrated by calculating the bending moment and stress thus added. Originally approved in This f8 increases to 2. The test methods have been used extensively in the trade for this purpose.
For proper gripping, it is desirable that the entire length of the serrated face of each wedge be in contact with the specimen. Combining values from the two systems may result in non-conformance with the standard.
