Calculation of principal stresses and their directions in selected cutting planes in rock drillingprincipal stresscore-drilling bitrockFEMThe paper is focused on the analysis of principal stress fields induced in the system of drilling tool-rock during the drilling process in immediate surroundings of ...
Principal stresses In the crowd of such stresses, there are some planes with only normal stresses acting on them. These normal stresses are called principal stresses and the planes are called principal planes. Principal stresses are the extreme values of normal stress that can exist when a structu...

It then follows that the inclination of the principal planes as well as the magnitude of the principal stresses will also vary. 因而可以得出,主平面的弯曲和主压应力的大小也会不同。 zhidao.baidu.com 2. These planes are commonly called the principal planes, and the stresses that act on them ...
These planes are called the principal planes of stress. The stresses acting on these planes—the maximum and minimum normal stresses—are called the principal stresses. Remark: For three-dimensional stress states, the three principal stresses (σ1, σ2, and σ3) are commonly ordered such that ...
aThe stresses on two planes having their normal vectors in the x-direction and the y-direction, which make an angle α with the directions of the major and the minor principal stresses, can be expressed into the major and the minor principal stresses by means of the equations of equilibrium...
