The article describes the phenomenon of degradation and dependencies with the variables involved in the dynamic problem are proposed, considering the mathematical formulation that characterizes the cumulative deformation and pore pressure generation associated with cyclical phenomenon. First, the necessary theoretical framework for the proper study of dynamic phenomena associated with the process of cyclic shear load is raised. Then, a new concept called "limit cycle" that serves as a reference for monitoring soil degradation is introduced. Finally, the fundamental variables involved in the study problem are identified and is raised, based on an earlier test campaign of an available research, the mathematical formulation that allows the characterization and quantification of the accumulated deformation and generation of pore pressure with the number of load cycles.Downloads
