Analysis and estimation of the yield strength of API X70 ...

Recommendations. API X70 and X80 linepipe steel sheets were shaped in the form of pipe with different strains (thickness/diameter ratio) by spiral pipe forming. Tension specimens taken from steel sheets or pipes at an interval of 2.5 mm were tested, and their yielding behavior, yield strength, and yield ratio before and after forming were analyzed.

Stress–strain curve - Wikipedia

The stress-strain curve for a ductile material can be approximated using the Ramberg-Osgood equation. This equation is straightforward to implement, and only requires the material's yield strength, ultimate strength, elastic modulus, and percent elongation.

Yield (engineering) - Wikipedia

Yielding means the start of breaking of fibers. Yield strength or yield stress is the material property defined as the stress at which a material begins to deform plastically whereas yield point is the point where nonlinear (elastic + plastic) deformation begins.

Yield Strength - Strength ( Mechanics ) of Materials ...

The yield strength is defined as the stress at which a predetermined amount of permanent deformation occurs. The graphical portion of the early stages of a tension test is used to evaluate yield strength. To find yield strength, the predetermined amount of permanent strain is set along the strain axis of the graph, to the right of the origin (zero). It is indicated in Figure 5 as Point (D).
