yield point stress

基本解释

When the stress reaches the yield point, a large increase in strain occurs with no increase in stress.
儅應力達到屈服點，應變會急劇增大而應力保持不變。
The volume dilatation and the non-linear deformation of rock originated, when the differential stress equals to the yield point of rock.
儅差應力達到巖石的屈服應力時，擴容和非線性應變開始。此外，隨應力水平的增加，擴容和非線性變形呈冪函數形式增加。
The yield point is the stress at which there is an appreciable increase in strain with no increase in stress, with the limitation that, if straining is continued, the stress will again increase.
屈服點是在應變有可觀增加，應力沒有增加的應力極限，在這個極限下，如果應變繼續增加，應力就也會增加。
