摘要
In the present paper, the influence of material substructures and of the inertia on the evolution of junctions among coherent discontinuity surfaces is discussed within the setting of multifield theories. An evolution equation for the junction is deduced in addition to the ones for the interfaces. The presence of substructures (or microstructures) within the body is evaluated through order parameters. Substructural interactions are considered and need to be balanced. The case in which such interactions can be decomposed into self-forces and microstresses is dealt with. Finally, the interfaces are endowed by peculiar structure: line stresses and microstresses are considered, as well as line substructural self-forces. (C) 2001 Elsevier Science Ltd.
