Abstract Present analysis dedicated to the dynamical investigation of anisotropic dark energy LRS Bianchi type-I cosmological model in the context of modified gravity in which Langrangian be the arbitrary function of Ricci scalar and Gouss-Bonnet invariant say f(R, G) gravity in the way of anisotropic fluid. The classification of the field equations towards f ( R , G ) = f 0 R m G 1 − m make available that the model is purely accelerating corresponds to 0 ≤ q ≤ − 1 . We govern the features of the derived cosmological model in view of the hybrid law inflation in bounce form (which involve power and de-Sitter cosmology) for the average scale factor. Also discussed the singularity of the model with the help of curvature of the model. It is observed that the model is fully engaged with both matter which exist initially for short expansion and dark energy dominated era and rests existing in quintessence dominated era and for sufficiently large time derived model forecasts that the anisotropy of the model will damp out and the Universe will turn out to be isotropic one and also observed that for quintessence dominated era the temperature and entropy density of anticipated model are positive definite along with some physical and kinematical parameters of the bounce model is also discussed in details.
