摘要

In this paper we consider the Cauchy problem for a higher-orderviscoelastic wave equation with finite memory and nonlinear logarithmic sourceterm. Under certain conditions on the initial data with negative initial energyand with certain class of relaxation functions, we prove a finite-time blow-upresult in the whole space. Moreover, the blow-up time is estimated explicitly.The upper bound and the lower bound for the blow up time are estimated.
