翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Differential stress ： ウィキペディア英語版 Differential stress Differential stress is the difference between the greatest and the least compressive stress experienced by an object. For both the geological and civil engineering convention $\backslash sigma\_1$ is the greatest compressive stress and $\backslash sigma\_3$ is the weakest, $\backslash !\backslash sigma\_D\; =\; \backslash sigma\_1\; -\; \backslash sigma\_3$. In other engineering fields and in physics, $\backslash sigma\_3$ is the greatest compressive stress and $\backslash sigma\_1$ is the weakest, so $\backslash !\backslash sigma\_D\; =\; \backslash sigma\_3\; -\; \backslash sigma\_1$. These conventions originated because geologists and civil engineers (especially soil mechanicians) are often concerned with failure in compression, while many other engineers are concerned with failure in tension. A further reason for the second convention is that it allows a positive stress to cause a compressible object to increase in size, making the sign convention self-consistent. In structural geology, differential stress is used to assess whether tensile or shear failure will occur when a Mohr circle (plotted using $\backslash sigma\_1$ and $\backslash sigma\_3$) touches the failure envelope of the rocks. If the differential stress is less than four times the tensile strength of the rock, then extensional failure will occur. If the differential stress is more than four times the tensile strength of the rock, then shear failure will occur.〔Cosgrove. J. W.
