In this paper, we are concerned with the blow-up of solutions for the following quasilinear hyperbolic equations system:
with the initial boundary value conditions
where Ω is a bounded open domain in with a smooth boundary ∂ Ω. and are real numbers, and () are given functions to be determined later.
When , problem (1.1)-(1.5) defines the motion of charged meson in an electromagnetic field and was proposed by Segal . Equations (1.1) and (1.2) with initial boundary conditions (1.3)-(1.5), but without dissipative terms, were early considered by several authors. Medeiros and Miranda ,  showed the existence and uniqueness of global weak solutions. Da Silva Ferreira  proved that the first-order energy decays exponentially in the presence of frictional local damping. Cavalcanti et al. considered the asymptotic behavior for an analogous hyperbolic-parabolic system, with boundary damping, using arguments from Komornik and Zuazua .
For the initial boundary value problem of a single quasilinear hyperbolic equation
Yang and Chen – studied problem (1.6)-(1.8) and obtained global existence results under the growth assumptions on the nonlinear terms and the initial value. These global existence results have been improved by Liu and Zhao  by using a new method. In , the author considered a similar problem to (1.6)-(1.8) and proved a blow-up result under the condition and that the initial energy is sufficiently negative. Messaoudi and Said-Houari  improved the results in  and showed that the blow-up takes place for negative initial data only regardless of the size of Ω. By means of the perturbed energy and the potential well methods, Messaoudi  gave precise decay rates for the solution of problem (1.6)-(1.8). In particular, he showed that for , the decay is exponential.
In absence of the strong damping , equation (1.6) becomes
For , it is well known that the damping term assures global existence and decay of the solution energy for arbitrary initial value (see –). For , the source term causes finite time blow-up of solutions with negative initial energy if (see ). When the quasilinear operator is replaced by , Wu and Tsai  showed that the solution is global in time under some conditions without the relation between p and r. They also proved that the local solution blows up in finite time if and the initial energy is nonnegative, and gave the decay estimates of the energy function and the lifespan of solutions.
In this paper we show that the local solutions of problem (1.1)-(1.5) with small positive initial energy blow up in finite time. Meanwhile, the lifespan of solutions is given. The main tool of the proof is a technique introduced by paper  and some estimates used firstly by Vitillaro  in order to study a class of single wave equations.
For simplicity of notations, hereafter we denote by the space norm, denotes norm, and we write an equivalent norm instead of norm . Moreover, C denotes various positive constants depending on the known constants and may be different at each appearance.
Concerning the functions and , we assume that

Therefore, we get that
Let , which implies that . As and , an elementary calculation shows that
Thus, has the maximum at and the maximum value is
In order to prove our main result, we need the following two lemmas.
Being the primitive of an integrable function, is absolutely continuous and equality (2.13) is satisfied.
Applying the idea of Vitillaro , we have the following lemma.
If , then for .
If , then there exists such that for .
For the detailed proof of Lemma 2.4, one can refer to .
We conclude this section by stating the local existence and uniqueness of solutions for problem (1.1)-(1.5), which can be obtained by a similar way as done in –, . The result reads as follows.
Suppose that, and
Moreover, at least one of the following statements holds true:

On the other hand, for , we have from Hölder’s inequality and Lemma 2.2 that
where . Let , , then . It follows from (3.12) that
Thus, we get from (3.24) that
Similarly, we have from Hölder’s inequality and (3.25) that
where . Integrating both sides of (3.30) over yields
