Formulas: Tensile Properties

Equation C-A-5-1

However, where strength evaluation is accomplished by load testing, the effects on yield strength of dynamic tensile testing should be accounted for in load test planning because yielding during the load test, where test loads are applied to the structure in a quasi-static manner, will tend to occur earlier than otherwise anticipated on the basis of a dynamic test yield strength. The static yield stress, $F_{y s}$, can be estimated from the specified minimum yield stress determined by routine application of ASTM methods, $F_{y}$, by the following equation (Ziemian, 2010):
