Standard Test Method for Ball Punch Deformation of Metallic Sheet Material

Importancia y uso:

4.1 The ball punch deformation test is widely used to evaluate and compare the formability of metallic sheet materials. Biaxial stretching is the predominant mode of deformation occurring during the test and, therefore, the results are most often used to rate or compare materials that are to be formed mainly by stretching. However, precise correlations between the cup height as determined by this test and the formability of a sheet material under production conditions have not been established.

4.2 Cup heights for specimens from the same sample can vary with differences in magnitude of hold-down force, lubrication, and method determining the of end point of the test. The procedures described in Sections 5, 7.1, and 7.3 will minimize these variations.
