  We consider the Randall-Sundrum braneworld theory with a single extra
dimension of infinite extent to investigate generalized $f(R)$ braneworld
models in the presence of several real scalar fields. In particular, we solve
the modified Einstein equations for the case of flat brane, with zero
cosmological constant, and for the case of bent brane, with a nonvanishing
cosmological constant. In both cases we found explicit solutions for the scalar
fields with analytical expressions for the respective warp factors.
