This paper is concerned with the existence of a global attractor for the nonlinear viscoelastic beam equation with past history memoryu tt + k Δ 2 u − ∫ − ∞ t μ ( t − τ )Δ 2 u ( τ ) dτ + f ( u ) + g (u t) = h ,where g ( u t ) is a damping like |  u t  |  r u t and f ( u ) is a source term like |  u  |  α u  − |  u  |  β u , by considering 0 ≤  β  <  α and r  > 0.
