![]() ![]() Although an extensive collection of stress concentration factors is tabulated in this chapter, a much larger collection is provided in Ref.Ħ.1 NOTATION The units for some of the definitions are given in parentheses, using L for length and F for force. The section variation that causes the stress concentration is referred to as a stress raiser. ![]() This increase in peak stress near holes, grooves, notches, sharp corners, cracks, and other changes in section is called stress concentration. Mathematical analysis and experimental measurement show that in a loaded structural member, near changes in the section, distributions of stress occur in which the peak stress reaches much larger magnitudes than does the average stress over the section.
