WebThe smaller of the two computed stresses is to be used. For combined stresses, as discussed in Section 10.4, the shear design stress is used. The code also applies a factor of 0.75 to the calculated design stress if the section being considered includes a keyway. It is noted that this is equivalent to a stress concentration factor of 1.33. Webuse it correctly. For a circular hole it is usually the width minus the diameter of the hole. Notably the thickness of a member containing a stress concentration does not enter into its value. K values for a circular hole centered in an axially loaded plate can be calculated using the formula (Roark and Young (1989)) K r W r W r W =− + −
