In polycrystalline elastic simulations grain boundaries can be considered as volume interphases or as elastic interfaces assuming a displacement jump across the interface Such an interface description does not account for the in-plane deformation of the interface and Poisson effects cannot be reproduced The purpose of this Note is to provide an enriched description of the elastic interface which takes into account such effects When considering a multilayer material the interphase description and the enriched interface description yield identica
