Abstract The Five dimensional anisotropic Bianchi type-III cosmological model has been investigated within the framework of Brans-Dicke (Phys. Rev. 124:925, 1961) scalar-tensor theory of gravitation. Dark Energy fluid and cosmic strings are considered as a source of energy-matter field and minimal interacting. To determine the solutions of field equations we have used Berman’s special law of variation, power law relation between scalar field ϕ and average scale factor a and proportionality between scalar expansion and shear scalar. It gives two model of the universe i.e. power law model and exponential model. Physicals and kinematical parameters of the model are also discussed for both the scenarios.
