tensile strength yield strength ts ys ratios of high
reflected by the ratio of yield strength and tensile strength of steel. By this standard , for the ratio YS/TS in range from 0.5 to 0.9 the coefficient k in the range from 3.54 to 3.21 (with increase the ratio YS/TS low value of k is recommended to use) is recommended to use. In
(yield ratio YR = YS/TS) of yield strength (YS) and tensile strength (TS). The same concept has been incor-porated in the STKN standard in Japanese Industrial Standards (JIS), which is the general standard for steel pipes used in column material applications. In the STKN standard, both the YS range and the TS range are speci-fied as 105 N/mm2 Role of Yield-to-Tensile Strength Ratio in the Design of minimum tensile strength of 450 MPa (65 ksi), and a maximum yield-to-tensile strength ratio of 0.85. Resulting F y/F u of A992 steel is between 0.77 and 0.85. In recent years A913/913M grade steels, which are high-strength low-alloy steel shapes of structural quality produced by a
the Tensile Strength and Yield Strength individually. It is the objective of this paper to explain the critical importance of considering the TS/YS ratio and for the engineering community to understand the importance of maintaining this ratio to 1.25 Specifying ratio of yield to ultimate tensile strength - TWIThe yield to tensile ratio of a line pipe material is a measure of the margin of safety against failure by plastic collapse, and indicates the ability of a pipe to experience plastic deformation before failure. Should the yield strength ( ) be equal to the ultimate tensile strength (UTS), any plastic deformation of the pipe could result in
The building codes such as American Concrete Institute (ACI) 318M-14 and Standard National Indonesia (SNI) 2847:2013 require that the ratio of tensile strength (TS) and yield strength (YS) should Tensile strength/yield strength (TS/YS) ratios of high The building codes such as American Concrete Institute (ACI) 318M-14 and Standard National Indonesia (SNI) 2847:2013 require that the ratio of tensile strength (TS) and yield strength (YS) should not less than 1.25. The requirement is based on the assumption that a capability of a structural member to develop inelastic rotation capacity is a function of the length of the yield region.
processing routes have had less effect on the ultimate tensile strength than on impeding the movement of dislocations which in turn governs the yield stress. Consequently, the Y/T ratio is higher for modern steels. The typical relationships between yield strength and Y/T ratio are shown in Fig. 3 from different sources(3,4). Since a low Yield stress / tensile stress ratio:Results of A high Y/T ratio is generally associated with a low strain hardening rate, N; the relationship however, shows considerable scatter. Steel specifications include upper limits to Y/T either inherently as the ratio between the minimum specified yield stress and ultimate tensile strength, or, in the case of certain offshore and linepipe grades, as
