In this work, I present exact cosmological solutions from Wesson’s induced matter model applied to a general 5D metric in $$f(R,T)$$f(R,T) theory of gravity. The non-conservation of the energy-momentum tensor, predicted by $$f(R,T)$$f(R,T) theory, allows the derivation of a relation that describes the time evolution of the extra coordinate, revealing its compactification. It is shown that such a compactification could induce the effects of an accelerated expansion in the observable universe.
