三维非线性弹性力学极限的不定常vonKármán壳方程

Yizhao Qin, Pengfei Yao

摘要:

本文研究了薄壳中三维非线性弹性动力学解的渐近性态,当薄壳的厚度$h$趋于零时。对于任意几何形状的壳体,在适当的作用力和初始数据的比例下,验证了非线性弹性动力学方程的三维解收敛于不定常vonKármán方程或动力学线性方程的解。

英文摘要:

The asymptotic behaviour of solutions of three-dimensional nonlinear elastodynamics in a thin shell is considered, as the thickness $h$ of the shell tends to zero. Given the appropriate scalings of the applied force and of the initial data in terms of $h,$ it's verified that three-dimensional solutions of the nonlinear elastodynamic equations converge to solutions of the time-dependent von Kármán equations or dynamic linear equations for shell of arbitrary geometry.
