The equivalent material concept (EMC), proposed recently by the author for predicting the tensile load-bearing capacity of ductile metallic materials weakened by V-notches, was utilized together with the mean stress (MS) criterion to estimate the experimentally obtained maximum loads that several ductile steel bolts with V-shaped threads can sustain. It was found that the MS-EMC criterion could estimate the experimental results successfully. By using the MS-EMC model, one can obtain well the tensile load-bearing capacity of V-threaded ductile steel bolts without conducting tensile fracture test.
