@article{Beau2012TheorieDC, title={Th\'eorie des champs des contraintes et d\'eformations en relativit\'e g\'en\'erale et expansion cosmologique: Theory of stress and strain fields in general relativity and cosmological expansion}, author={Mathieu Beau}, journal={arXiv: General Relativity and Quantum Cosmology}, year={2012} }

In this article we propose to add stress-energy tensor to the Einstein equations, assuming that the matter-energy and the metric space-time is nothing but a continuous medium with some elastic properties. We first give a general expression of the stress tensor which is linearly related to the strain tensor. Then, we give the particular expression of the stress tensor for a spatially homnogeneous and isotropic cosmological medium. After that we derive the modified Friedmann equations. In first…
