On Korn

Web1 jan. 2024 · The Korn inequality ( K p) is a fundamental tool in the theory of elasticity and fluid mechanics; we refer the reader to [1], [3], [6], [7], [8], [10], [13], [19] and the references therein. The validity of Korn's inequality is closely related to the geometry of the domains under consideration. Let us review some earlier results.

WebThe proof, very similar to that one in [10], is complicated and the method applies only to the case n = 3. If F(x) = F does not depend on x, inequality (1.1) is quite easy to obtain: after suitable affine transformation it reduces to the classical Korn’s Inequality. The WebKorn’s inequalities on a surface constitute the keystone for establishing the existence and uniqueness of solutions to various linearly elastic shell problems. As a rule, they are, however, somewhat delicate to establish.
