By some differential inequalities, we derive the finite time blow up results and the estimates of the upper bound blowup time with arbitrary positive initial energy. We also discuss the influence mechanism of the linear weak damping and strong damping on blowup time, respectively.", keywords = "fourth-order strain wave equation, arbitrary positive initial energy, blowup, blowup time", issn = "1232-9274" }
