ABSTRACT
This paper deals with a nonlinear viscoelastic equation. The aim is to expand the class of the function of relaxation that ensuring a general decay. We adopt the following commonly condition on relaxation function
:
, where ξ is a nonincreasing function and χ is an increasing and convex function on the whole
instead of is convex only near the origin in the literature.
