ASTM B 831 Standard Test Method for Shear Testing of Thin Aluminum Alloy Products

ASTM B 831 covers single shear testing of thin wrought and cast aluminum alloy products to determine shear ultimate strengths.

It is intended for products that are too thin to be tested according to Test Method B769.

The intent of ASTM B 831 test method is to provide a means of measuring the ultimate shear strength of thin aluminum alloy wrought and cast products.

It is recognized that the loading conditions developed by this test method, and by most others, are not ideal in that they do not strictly satisfy the definitions

of pure shear. However, rarely do pure shear conditions exist in structures.

NOTE 1: Results from this test method are not interchangeable with results from Test Methods B565 and B769.

Shear strengths obtained by this test method have been shown to differ from values determined with other methods.3
