讨论具记忆项的Euler-Bernoulli梁方程的初边值问题.利用改进的凸性分析方法,证明了当初始能量为负时解的爆破性质.
This paper discussed the initial-boundary problem of Euler-Bernoulli beam equation with memory. By using the improved method of convexity analysis, the nonexistence of global solutions for this problem is proved when initial energy is negative.
