Entanglement and Bell nonlocality had been considered equivalent manifestations of the non classicality of some quantum states. Nowadays, it is well known that they are distinct concepts, despite the fact that the intricate relations between them are still not well understood. This project has the goal to investigate those relations by means of a new method, that takes into account compatibility relations between measurements of each party of the scenario. By means of this method, it is possible to obtain new Bell inequalities capable of identifying the nonlocality of entangled states that appear to be local. Also, it offers a unified approach for the concomitant study of Bell nonlocality and contextually -- a nonclassical manifestation of quantum systems, as nonlocality -- in the same physical scenario.
