tangent relationship

The conception of virtual work was modified by defining the tangent of a rotating angle of a cross-section as the rotational displacement and explaining the relationship of forces and displacements as forces not dragging along the displacements.

提出了用截面转角的正切值定义截面的转动位移，并将虚功中力和位移的关系描述为力不随位移拖动的模式。

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。
