Abstract
Obravnavan je problem modeliranja odrezavanja dolivkov (narejenih iz zlitine EN AC-46000) z metodo končnih elementov. Fenomen porušitve je modeliran na dva načina: Z razširjeno metodo končnih elementov in duktilnim kriterijem v okviru eksplicitne sheme. Rezultati numeričnih simulacij so primerjani z analitično in eksperimentalno določenimi. Izkaže se, da je duktilni kriterij bolj primeren za modeliranje obravnavanega problema.

Title:
COMPUTER SIMULATION OF THE AL INGATES CUTTING PROCESS
Abstract:
In this work we consider the problem of modelling of ingates cutting process (made of EN AC-46000 alloy) with finite element method. The phenomenon was modeled with extended finite element method and with ductile criterion using the explicit scheme. The results obtained with numerical simulations are compared to those obtained using analytical methods and experiments. We can conclude that the use of ductile criterion is more appropriate when modelling beforementioned problems.
