Contact Erosion
After providing a brief presentation of the conditions leading to the occurrence of the contact erosion (CE) phenomenon in a structure, this chapter focuses on the problem of CE according to three different scales in order to deal with the subject as exhaustively as possible. The three different scales are at sample scale, at pore scale, and at hydraulic structure scale. The different macroscopic approaches presented are aimed at characterizing and, in certain cases, modeling CE phenomena using averaged magnitudes on a sample representative of a two‐layered material. These large‐scale tests showed that the impact of spatial scale was low and even zero with respect to the hydraulic initiation threshold of CE.
