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.
当应力达到屈服点，应变会急剧增大而应力保持不变。
The volume dilatation and the non-linear deformation of rock originated, when the differential stress equals to the yield point of rock.
当差应力达到岩石的屈服应力时，扩容和非线性应变开始。此外，随应力水平的增加，扩容和非线性变形呈幂函数形式增加。
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.
屈服点是在应变有可观增加，应力没有增加的应力极限，在这个极限下，如果应变继续增加，应力就也会增加。
