“…As a result, researchers are increasingly interested in string cosmological models, both in general relativity and alternative theories of gravitation. [6,19,[38][39][40][41][42][43][44][45][46] are some authors who have studied various aspects of string cosmological models in general relativity.…”

When the source for the energy-momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings, a spatially homogeneous and anisotropic Bianchi type-V cosmological model is considered in this paper in a scalar-tensor theory of gravitation proposed by Saez-Ballester, we derive a determinate solution utilizing the plausible physical conditions: (i) the scalar of spacetime expansion is proportional to the shear scalar; (ii) the baratropic equation of state for pressure and density; and (iii) the bulk viscous pressure is related to the energy density. The model's physical and kinematic features are also discussed.
