<p>This paper provides a rapid overview of the mechanics of cohesive granular materials and powders, with a particular focus on the development of constitutive equations for the steady flowing regime. We begin by reviewing the various sources of adhesion between particles, before exploring the onset of flow in cohesive materials. While yield conditions are central to many characterization methods, they provide limited insight into flow behavior. We then discuss recent studies on the flow of cohesive granular materials, emphasizing the development of constitutive equations. A direct comparison of results from DEM simulations across different studies highlights the importance of the interaction model details but reveals key insights into the relevance of different dimensionless numbers, paving the way for a more comprehensive rheological description of powders.</p>
