振动薄板的大时间存在性

Large Time Existence for Thin Vibrating Plates

H. Abels, M. G. Mora, S. Müller

摘要:

我们构造了一个由非线性弹性动力学描述的振动薄板的非线性波动方程的强解。对于足够小的厚度,我们得到了强解的存在性为大的时间在适当的缩放的初始值,使极限系统$h\to 0$是非线性von Kármán板方程或线性四阶Germain-Lagrange方程。在线性Germain-Lagrange方程的情况下,我们甚至得到三维解到二维线性板方程解的收敛速度。

英文摘要:

We construct strong solutions for a nonlinear wave equation for a thin vibrating plate described by nonlinear elastodynamics. For sufficiently small thickness we obtain existence of strong solutions for large times under appropriate scaling of the initial values such that the limit system as $h\to 0$ is either the nonlinear von Kármán plate equation or the linear fourth order Germain-Lagrange equation. In the case of the linear Germain-Lagrange equation we even obtain a convergence rate of the three-dimensional solution to the solution of the two-dimensional linear plate equation.
