In this paper, the dynamical behavior of the anisotropic universe has been investigated in f(R,T) theory of gravity. The functional f(R,T) has been rescaled in the form f(R,T) = μR + μT, where R is the Ricci scalar and T is the trace of energy momentum tensor. Three cosmological models are constructed using the power law expansion in Bianchi type V Ih (BV Ih) universe for three different values of h = −1, 0, 1, where the matter field is considered to be of bulk viscous fluid. It is observed that the anisotropic BV Ih model in the modified theory of gravity is in agreement with a quintessence phase for the value of h = −1 and 0. We could not obtain a viable cosmological model in accordance with the present day observations for h = 1. The bulk viscous coefficient in both the cases are found to be positive and remain constant at late time. The physical behaviors of the models along with the energy conditions are also studied.
