研究了具非线性阻尼和源项的Timoshenko方程初边值问题整体解的不存在性.对正初始能量和适当的初始条件,利用一个微分不等式给出了Timoshenko梁方程初边值问题整体解的不存在的充分条件.

英文摘要：

A kind of one-dimensional Timoshenko model for beam with nonlinear damping and source terms was investigated.By a differential inequality,for positive initial energy and appropriate initial datum,a sufficient condition for the global nonexistence of solution to the Timoshenko system was given.
