Proof load stress คือ

WebDec 12, 2014 · Proof strength, or proof load, is the full size equivalent of a yield test. Yield testing is typically only performed on machined specimens. In most fastener standards, full size testing is the preferred method, and the referee method if there is a discrepancy … WebHowever, since the stress is highly localized and triaxial, the stress intensity may be very high (above the yield point) without producing apparent damage. Since this is the case and the formulas in Table 11-1 hold only in the elastic range, the empirical formulas for allowable loads given in Section 11.7 are most useful for practical design.
