Abstract
In this work, we consider a quasilinear system of viscoelastic equations with degenerate damping and source terms without the Kirchhoff term. Under suitable hypothesis, we study the blow-up of solutions.

Summary
We consider the following problem:. f2(u, v), (x, t) ∈ Ω ×(0, T), u(x, t) v(x, t) 0, (x, t) ∈zΩ u(x, 0) u0(x), ut(x, 0) u1(x),. G1(u, ut) |ut|j− 2ut e author proved general and optimal decay of solutions. En, in [14], the author investigated the same problem without damping term and established a general decay of solutions. In problem (1) with η 0, in [15], Wu proved a general decay of solutions. In [16], Piskin and Ekinci established a general decay and blow-up of solutions with nonpositive initial energy for problem (1) case (Kirchhoff type). Some other authors investigate the hyperbolic type system with degenerate damping terms (see [17,18,19,20]). Under some restrictions on the initial datum and standard conditions on relaxation functions, the authors have established the global existence and proved the general decay of solutions. We give some concluding remarks in the last section
