WebPer Shigley, the proof strength is approximately equal to 85% of the tensile yield strength, S ty. Based on S proof = 0.85·S ty, the recommended preload force as a function of yield strength is: Considering that the above values are conservative, a general rule of thumb is to preload the fastener to 2/3 of the yield strength (i.e., % yld = 66.7%). WebJun 20, 2003 · Try to find out what ED the handbook values are based on. I do not have the HDBK at hand now, but I think it might be 1.5D. Not sure though. The designed ED is usually 2D+ some company figure, maybe 2.5mm to account for misdrilled holes, oversized repair rivets etc. I recollect that a 1.5D ED has 80% strength of a 2D ED.
