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 $\sigma_1$ is the greatest compressive stress and $\sigma_3$ is the weakest,

$\!\sigma_D = \sigma_1 - \sigma_3$ .

In other engineering fields and in physics, $\sigma_3$ is the greatest compressive stress and $\sigma_1$ is the weakest, so
