Big Rip Scenario in Brans-Dicke Theory

In this work, we present a Big Rip scenario within the framework of generalized Brans-Dicke (GBD) theory. GBD theory, consider an evolving BD parameter along with self-interacting potential. An anisotropic background is considered to have more general view cosmic expansion. The theory cosmological constant presented as effective fluid relativity which favours phantom field dominated phase. model parameters are constrained so that provides reasonable estimates Hubble and other recent observational aspects at epoch. dynamical scalar been analysed. It found witnesses finite time doomsday tBR≃16.14Gyr, for scenario, requires large negative value parameter.
