“…Note that mesh superposition or submodeling techniques, which use a coarse mesh over the whole model plus a geometrically independent much finer mesh in regions of interest, compare e.g. Takano et al (2001), are conceptually closely related to embedding schemes.…”

“…Till date, the accuracy and efficiency in modeling have been confirmed in the 2D analysis for the locally existing inclusion/void (Takano et al, 2000b), microscopic crack behavior affected by reinforcing fibers (Takano et al, 2001b), and interface crack behavior affected by pores (Takano et al, 2003b).…”

“…The microscopic heterogeneity is modeled directly on the microscopic mesh and local heterogeneity such as void, inclusion, crack, interface, etc. (Takano et al, 2000b(Takano et al, , 2001b(Takano et al, , 2003b.…”

“…Secondo tale approccio, la struttura eterogenea reale è descritta da un modello di materiale costituito da un nucleo (core) contenente un arrangiamento discreto delle fasi, inserito in una regione omogenea a cui sono generalmente applicati i carichi (deformazioni e tensioni). La legge costitutiva della regione esterna al nucleo eterogeneo è solitamente quella macroscopica del materiale, nota a priori o determinabile nel caso di modelli di tipo self-consistent, [19][20][21]. Infine, le tecniche di modellazione che si basano sul Windowing approach, prevedono la costruzione di sub-regioni ("windows") rettangolari o esaedriche ricavate in modo casuale a partire dalla microstruttura reale, e sottoposte ad appropriate condizioni al contorno, [22].…”
