The paper presents the recent advances and their relevance in the study of the geomechanical behavior of shales considering both experimental and modelling aspects. Shales are involved in several energy-related engineering applications where complex multiphysical conditions are encountered. Partial saturation, non-isothermal conditions, plasticity and damage mechanisms may have a fundamental impact on their geomechanical behavior. The relevance of these aspects for shales is presented in the paper both from advance experimental and modeling point of view.
