摘要：
In this paper, we consider a dissipative singularly non-autonomous semilinear problem in thermoelasticity for N-dimensional materials. Under suitable conditions on nonlinearity and functional parameters, we prove a result of existence of pullback attractor via decomposition of the displacement vector field motivated by Helmholtz decomposition from vector calculus.
