英语词汇“upper yield point”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

yield-point n. (the stress corresponding to) the point on a stress–strain diagram at which the strain begins to increase substantially without a corresponding increase in stress: in some metals differentiated as upper yield point, a point at which the stress ceases to increase as the strain increases, prior to a fall to the lower yield point, from which the strain increases while the stress remains almost constant at the lower value; also, esp. in Geology, the elastic limit or the yield strength.

1870 G. Berkeley in Exper. Mech. & Other Properties Steel 4 Within the ‘yielding point’ of Steel the amount of lengthening from tension, or shortening from compression, produced by equal forces per unit of area is nearly the same.]

1886 K. Pearson in I. Todhunter Hist. Theory Elasticity & Strength of Materials I. 887 When a bar is subjected to increasing traction, a certain stretch is reached after which there is a sudden and rapid increase of stretch... The point at which this change takes place is very marked, and various names have been suggested for it, as the limit of fatigue, the limit of stability, and the break-down point. The latter name brings out the character of the phenomenon, but at the same time suggests a point related to absolute strength or cohesion; I have therefore spoken of this point in the present work as the yield-point.

1889 Telegr. Jrnl. & Electr. Rev. 20 Dec. 707/1 The question of discontinuity of the curves about the ‘yield point’ was next discussed.

1919 Fuller & Johnston Appl. Mech. II. x. 378 If the material is very ductile a yield point in torsion will appear at a torque somewhat higher than the elastic limit, similar to the yield point in tension.
