Describing curved space-time as a four-dimensional manifold strained by the presence of matter or of texture defects, an additional term in the Lagrangian of space-time has to be introduced besides the Ricci scalar, accounting for the strain. The additional term produces dark matter-like effects around any given body. These effects show up both in the angular speed of freely orbiting objects and in the gravitational lensing of light. These results are obtained and discussed while treating a spherically symmetric stationary space-time configuration.
