Fractures and Defects in Cosserat Continua Modelling Layered Materials

摘要: This paper considers fracture of layered materials consisting many layers that are thin compared to the characteristic size loading (eg, wave length). In this case explicit modelling fracturing every layer becomes cumbersome. Instead, we represent material as an equivalent continuum provides a large-scale (average) description response loading. is achieved by introducing volume elements much greater than thickness and, at same time, smaller length stress variations. It should be noted in approach no lengths element can distinguished.
