Webrail steel were derived from the wear volume analysis using Archard’s wear model. The material interface bond strength was evaluated from shear testing and analysis to measure the shear interface strength of the metallurgical bond between deposited material on a rail steel substrate. Show less WebDec 1, 2002 · If a published bearing strength value is unavailable, for ductile metals it can generally be approximated as 1.5 times Sty or Stu, for edge distance to bolt hole diameter ratio e/D h = 2.0. For ductile metals, shear yield strength Ssy can be taken as 0.577 Sty. And shear ultimate strength Ssu = 0.62 Stu sounds plausible in the absence of a ...
