Saint-Venant's Compatibility Condition
In the mathematical theory of elasticity the strain is related to a displacement field by
Barré de Saint-Venant derived the compatibility condition for an arbitrary symmetric second rank tensor field to be of this form, this has now been generalized to higher rank symmetric tensor fields.

Famous quotes containing the word condition:
“The pendulum oscillates between these two terms: Suffering—that opens a window on the real and is the main condition of the artistic experience, and Boredom ... that must be considered as the most tolerable because the most durable of human evils.”
—Samuel Beckett (1906–1989)
