“…However, these authors simulated only the initial regime of yielding but not the coalescence stage. Bonora and Ruggiero [18] modeled the graphite particles also as unbonded and elastic but incorporated the cooling from solidification to room temperature. The different thermal shrinkage of graphite and matrix during cooling leads to compressive stresses at the graphite matrix interface at room temperature.…”

“…The graphite nodules are modeled as zones with very low Young's modulus [18,21,22,19,25], while the ferritic matrix is considered as an elastoplastic medium with power law hardening…”

“…Upon loading, ductile fracture is caused by nodule/matrix debonding, void growth and coalescence [18,19,20]. Literature data [18,21,22,19] show that the nodules can be modeled as voids since their stress-carrying capacity is very small in tension. Such hypothesis will be made herein.…”

“…La microstruttura della ghisa sferoidale bene si presta ad una schematizzazione secondo la ripetizione di una cella elementare che contenga tutte le informazioni necessarie, poiché i noduli di grafite sono distribuiti abbastanza uniformemente nella matrice, le loro dimensioni non sono troppo dissimili, e la distribuzione delle fasi ha una caratteristica ben distinta (ciascun nodulo è incapsulato dalla fase ferritica). Diversi lavori sono reperibili in letteratura sull'utilizzo di celle unitarie per lo studio e la previsione del comportamento meccanico della ghisa nodulare, inerenti le proprietà elastiche, la simulazione del danneggiamento, o l'effetto della presenza di tensioni termiche, [31][32][33][34]. In un lavoro del presente autore [35] si è presentato un modello a cella unitaria della ghisa nodulare, mostrato in Fig.…”
