摘要
利用Galerkin方法,研究了一类具有结构阻尼的kirchhoff型波动方程,方程是截面弹性杆运动的模型.通过各种不等式技巧及算子半群理论,证明了方程的解半群具有全局吸引子.
In this paper,a kind of Kirchhoff type Wave Equation with strong Damping is studied by Galerkin,which arise from the cross-section motion of elastic rod.It proved that the related continuous semigroup s(t)has a global attractor which is connected.
