Original abstract

The present work deals with a strain intensity sensitivity to finite element mesh density in computational models of skull bone sample with an inhomogeneous distribution of Young's modulus. Computational experiments on models with various mesh density were conducted to test the hypothesis that the strain intensity distribution along the bone sample thickness is significantly influenced by the mesh density when material properties of bone obtained from the computer tomography are assigned to the finite element model. The results indicate that the mesh quality matters.

Czech abstract

Předkládaná práce se zabývá citlivostí analýzou hustoty sítě konečných prvků na intenzitu přetvoření ve vzorku lebeční kosti s nehomogenní distribucí Youngova modulu pružnosti. Výpočtové experimenty na modelech s různou hustotou sítě byly provedeny za účelem testování hypotézy, že distribuce intenzity kmenu podél tloušťky vzorku kosti je významně ovlivněna hustotou sítě, když jsou materiálové vlastnosti kosti získané z počítačové tomografie přiřazeny modelu konečných prvků. Výsledky naznačují, že kvalita sítě je důležitá.
