Abstract In this paper, we consider the following Timoshenko system of
thermo-viscoelasticity of type III with frictional damping and delay terms: { ρ
1 φ t t - K ( φ x + ψ ) x = 0 , ( x , t ) ∈ ( 0 , 1 ) × ( 0 , ∞ ) , ρ 2
ψ t t - b ψ x x + K ( φ x + ψ ) + β θ x = 0 , ( x , t ) ∈ ( 0 , 1 ) ×
( 0 , ∞ ) , ρ 3 θ t t - δ θ x x + γ ψ t t x + ∫ 0 t g ( t - s )
