摘要
考虑具有介质阻尼及非线性粘弹性本构关系的梁方程,证明了它的有界吸收集和有限维惯性流形的存在性,并由此得到在一定的条件下所给偏微分方程等价于一常微分方程组的初值问题。
The equations of nonlinear viscouselastic beam are considered, The existence of absorbing set and inertial manifolds for the system are obtained, and from which we get that the P D E. is equivalent to a system of ordinary differential equations under some conditions.
