Cilem diplomove prace bylo posouzeni miry shody mechanickych vlastnosti odlitku z litiny s lupinkovym grafitem s mechanickymi vlastnostmi vyhodnocenymi pomoci numericke simulace v softwaru MAGMA5. Hodnoceni mechanickych vlastnosti bylo zamereno na tvrdost a mez pevnosti v tahu v ruznych mistech odlitku. Teoreticka cast se zabyva klasifikaci litin, strukturnimi slozkami litiny s lupinkovym grafitem a faktory urcujicimi vysledne mechanicke vlastnosti materialu. Prakticka cast prezentuje pokus o nalezeni empirickych zavislosti mezi vstupnimi parametry a vysledky vyhodnocenymi pomoci simulacniho softwaru. V posledni casti se prace zabyva porovnanim vysledku realnych se simulovanymi mechanickymi vlastnostmi.
The aim of this thesis was to assess the degree of conformity between the mechanical properties evaluated by numerical simulation in software MAGMA5 and the measured values of hardness and ultimate tensile strength of lamellar graphite iron castings. The theoretical part of this thesis deals with the classification of cast iron, structural components of lamellar graphite iron, and the factors defining the resulting mechanical properties of the material. The practical part presents an attempt to find empirical dependencies between input parameters and results evaluated by simulation software. At the end, an analysis of the correlation between reality and simulation software is performed.
