We establish thresholds for global existence versus blow-up using the potential well method which relies essentially on the ideas suggested by Payne and Sattinger. Our results improve the global existence and blow-up results given in the literature for the present class of nonlocal nonlinear wave equations and cover those given for many well-known nonlinear dispersive wave equations such as the so-called double-dispersion equation and the traditional Boussinesq-type equations, as special cases.engopenAccessarticle9431332200032748360002510.1016/j.na.2013.09.013Nonlocal Cauchy problemGlobal existenceBlow-upPotential wellBoussinesq equationDouble dispersion equation2-s2.0-84885158143
