用加强的平坦性条件,讨论非线性可拉伸梁方程的长时间动力学行为.在非线性项条件减弱的情形下,先验证解半群的渐近紧性,进而运用加强的平坦性条件,得到了更一般的具有强阻尼的非线性可拉伸梁方程指数吸引子的存在性.
We investigated the long-time dynamic behavior of the nonlinear extensible beam equations by enhanced flattening property.Under the weaker condition of the nonlinearity,we first verified the asymptotic compactness of solution semigroup,and then used the enhanced flattening property,we obtained the existence of exponential attractors for the general nonlinear extensible beam equations with strong damping.
