In this paper we consider a nonlinear class viscoelastic plate equation with a lower order by perturbation of -Laplace operator of the form associated with initial and Dirichlet–Neumann boundary conditions.
Under suitable conditions on and the variable exponent of the -Laplace operator, we prove a blow up in finite time with negative initial energy in the presence of a strong damping acting in the domain. This equation corresponds to a viscoelastic version arising in dynamics of elastoplastic flows and plate vibrations.

在本文中,我们通过扰动来考虑具有较低阶的非线性类粘弹性板方程 -表格的拉普拉斯运算符 与初始和Dirichlet-Neumann边界条件相关。
在合适的条件下 和变量的指数 -拉普拉斯算子,我们证明了在强阻尼存在下具有负初始能量的有限时间内的爆炸 在领域中行动。该方程对应于在弹塑性流动和板振动的动力学中产生的粘弹性形式。
