Abstract
The correction functions that can be used to determine the stress state of a flattened disk specimen in diametral testing are provided by referring to the analytical solutions for arc- and point-loaded circular specimens. The stress components at three important locations in the flattened specimen (with varying degrees of truncation, w) were obtained numerically by finite element analysis, and compared with the analytical solutions at the center of the arc- and point-loaded specimens. The correction functions, which are provided as a function of w, can be useful tools for the analysis of the stress state and for the design of the flattened disk specimen in diametral testing.
