We study the Cauchy problem for a class of strongly damped multidimensional generalized Boussinesq equationsutt−Δu−Δutt+Δ2u+Δ2utt−kΔut=Δf(u), wherekis a positive constant. Under some assumptions and by using potential well method, we prove the existence and nonexistence of global weak solution without solution without establishing the local existence theory.
