Provide the sample specimen dimensions for tensile tests: 12.5 mm wide and 19 mm thick, according to the relevant ASTM E standards.

Answer :

Final answer:

ASTM E8 standard outlines tensile testing procedures with adaptable specimen dimensions based on material size and test goals. It assesses properties including yield strength, ultimate tensile strength, and elongation.

Explanation:

The ASTM E8/E8M - 16ae1 standard provides protocols for tensile testing of metallic materials. As per this standard, the dimensions for the test specimens depend on the type of product (e.g., sheet, bar, etc.), its size, and thickness. However, there is no exact size defined for a 12.5 mm wide and 19 mm thick sample.

A common flat specimen dimension for a thickness over 0.5 in (or 12.7 mm) is 2 in (or 50.8 mm) wide, which is larger than your specified width of 12.5 mm. The gauge length can be 4 in (or 101.6 mm). Always remember that the standard allows some flexibility to adjust the dimensions based on the material and the objectives of the test.

Tensile testing is done to determine properties such as yield strength, ultimate tensile strength, elongation, and reduction of area which are crucial for material selection in engineering applications. It is done by applying a force that pulls the material apart while measuring the deformation (or strain), which is the change in length relative to its original length.
