The aim of this manuscript is to explore cosmological solutions using the modified f(T, B) theory of gravity, where B represents the boundary scalar term and T represents the torsion scalar. For our current work, we consider the Friedmann–Robertson–Walker spacetime to obtain solutions. We investigate the nature of the universe under various scenarios, including acceleration expansion of universe, ultra-relativistic universe, sub-relativistic universe, dust universe, radiation universe and stiff universes. Moreover, we choose power-law technique to study the expanding nature of the universe by taking two different f(T, B) gravity models. Additionally, we discuss the bouncing scenario of universe and observe the energy conditions, which must be satisfied for a successful bouncing model by selecting particular values for the model parameters. It can be concluded that some solutions in f(T, B) gravity models support the concept of exotic matter and accelerated expansion of the universe due to a large amount of negative pressure.
