（重定向自Airy stress function）

In linear elasticity, the equations describing the deformation of an elastic body subject only to surface forces (&/or body forces that could be expressed as potentials) on the boundary are (using index notation) the equilibrium equation:

where $\sigma$ is the stress tensor, and the Beltrami-Michell compatibility equations:
