The present paper deals with a novel method to predict the effective elastic behavior of heterogeneous continuous materials using discrete element method. This work uses a numerical approach based on a hybrid particulatelattice model in which discrete elements are linked by cohesive forces through beam elements. Mechanical tests, carried out on particulate composite material, are performed in terms of effective elastic properties and stress fields which exhibit a good adequation with other numerical and analytical approaches such as the finite element method and the Fast Fourier Transform based method. As an example, the proposed approach is performed to predict the elastic properties of a ceramic/resin composite as well as the local effects by means of equivalent Von Mises stress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
