Abstract
We study the big rip scienario in Swiss-cheese Brane-worlds. The results obtained have been found to be independent of the value of the cosmological constant whether its positive, negative or zero. Negative tension branes are not allowed in the current model. There is a sign flipping in cosmic pressure corresponding to the sign flipping in the deceleration parameter from positive to negative. The evolution of the EOS parameter shows the presence of three phases: the matter dominant decelerating era,The accelerated-Quitessence phase, and the phantom phase. The evolution of the potential and Kinetic term also shows a change of sign. The energy conditions and cosmographic parameters have also been investigated.
