In this paper, we search the existence of the Bianchi-V string cosmological model in the f (R, T) gravity with power law expansion. Einstein’s field equations have been solved by taking into account the law of variation of Hubble’s parameter that yields the constant value of the deceleration parameter (DP). We observe that the massive strings dominate the early universe but they do not survive for long time and finally disappear from the universe. We examine the nature of classical potential and also discuss the physical properties of the universe.
