The role of tensor force is investigated by using the time-dependent Hartree-Fock (TDHF) theory in the collision 16O+40Ca. The full tensor force is incorporated in our TDHF implementation. The calculations are performed in three-dimensional Cartesian coordinate without any symmetry restrictions. We study the effect of tensor force on Coulomb barrier, upper fusion threshold energy, and energy contribution of the time-odd and tensor terms in Skyrme energy functional. The Coulomb barrier obtained from the energy functional with frozen density approximation is compared with the available experimental data. We find that the tensor force may change the upper fusion threshold energy in the order of a few MeV for the collision 16O+40Ca. The tensor force has a non-negligible effect in heavy-ion collisions.
