Abstract
For the nonlinear wave equationu tt -Nu +G(t,u, u t ) = ℱ in Hilbert space, with associated homogeneous initial data, we show how ana priori bound of the form ∫ T0 ∥G(τ,u, u τ)∥2 dτ ≤ κ ∫ T0 ∥ℱ(τ)∥2 dτ leads to upper and lower bounds for ∥u∥ in terms of ∥ℱ∥. An application to nonlinear elastodynamics is presented.
Zusammenfassung
Für die nicht-lineare Wellengleichungu tt -Nu +G(t,u, u t ) = ℱ in einem Hilbert Raum mit zugehörigen Anfangsbedingungen zeigen wir wie eine vorgegebene Schranke von der Form
zu oberen und unteren Schranken für ∥u∥ in Abhängigkeit von ℱ führt. Eine Anwendung auf nichtlineare Elastodynamik wird gezeigt.
