Nonlocal interface mechanical models

Risultato della ricerca: Chapter

Abstract

The paper presents a nonlocal elastic damage-frictional interface model. The reason tointroduce nonlocal mechanical features inside the constitutive relations is justified by the fact thatthere are several circumstances, in which the interface displays inside an extended process zone withmicrostructural spatial interactions. Typically, spatial bridging mechanical effects can be effectivelymodeled by integral (strongly nonlocal) stress-strain relations. The paper develops an elastic nonlocalmodel with local isotropic damage and the relations are constructed following a thermodynamicalconsistent approach.
