This chapter presents an overview of modeling frameworks available within the theory of elastoplasticity and able to capture main features of shale behavior including: yield under compression, failure under deviatoric strain, strain-softening, degradation, anisotropy of elastic moduli, strength and permeability, as well as creep and viscous response. For each aspect, a short illustration of material response is presented, followed by a brief presentation of the mathematical formulation used to capture it. When numerical simulations of real cases are available, the ability of the models to reproduce laboratory and field measurements is also presented.
