Poisson's ratio

When compressive stress reaches zero, a critical value of the post-peak Poisson's ratio is achieved.

当压缩应力降至零时, 峰后泊松比达到临界值.

The result shows that the tangent Poisson's ratio computed with the relationship proposed by Daniel is in conformity with the testing data, but the value obtained by assuming the relationship between the axial strain and lateral strain as hyperbola differs from the testing data.

试验还表明，高压力下的切线泊松比，用但尼尔建议的方法进行计算与实测资料相符，用轴向应变与侧向应变为双曲线关系的假设进行计算则相差较大。

Poisson's ratio represents the negative ratio of transverse and longitudinal strains.

泊松比的定义为样品横向应变与轴向应变的相反数。

In this paper, the tangent modulus and the tangent Poisson's ratio computed with internal friction angle under convenient pressure and with non-linear variability of strength under high pressure were compared.
