Aluminum sheet tensile test, the sample direction is horizontal or vertical sampling? What is the relationship between the longitudinal specimen, the transverse specimen and the rolling direction of the sheet?
In some cases, the tensile test specimen orientation is consistent with the rolling direction
Sampling is generally longitudinal (rolling direction) taken by horizontal agreement by both parties
If the test sample strength, then the proposed horizontal specimens, vertical and horizontal differences is caused by the rolling, rolling in the plate during the process, the metal in the rolling direction of the extension of the grain in the rolling direction of elongation, and the formation of Regular band arrangement, which is often said that the fiber structure and texture, resulting in anisotropy, in general, along the rolling direction of the material strength and elongation.
In general, we do the tensile test are selected longitudinal, we usually refer to the longitudinal direction of the plate rolling (commonly known as the X-axis direction), because of its rolling in general tensile strength than the lateral High, horizontal is generally perpendicular to the rolling direction, of course, some of the material is longitudinal rolling, horizontal stretch, such as some thin film materials, usually through the stretch of the lateral stretch than did not have to stretch the big.
?? Another tensile test depends on your main focus on the performance, different performance depends on the different indicators of data.
