design stress factor的意思|示意

This value is used to compare the strength of materials, but a safety factor is applied when making design calculations, to bring the working stress well below the limit of proportionality.

此值被用来比较材料的强度，但是当设计计算时，要用一个安全系数，使工作应力低于比例限制。

If stress concentration factor expression for rectangular drift opening is known, it can be of great help in the design and support of mine horizontal rectangular drift.

若能了解矩形巷道孔边的应力集中系数表达式，则对矿山水平矩形巷道的设计和支护都有很大的帮助。

As nonlinear factor of displacement is not taken into account in design of thermal overhead pipeline previously, actual stress condition of pipeline and support can't be reacted correctly.

原先热力架空管道的计算没有考虑到位移的非线性因素，不能正确地反映管道和支座的实际受力情况，现结合热力架空管道和支座的受力情况，给出了力学的计算模型。
