Plastomehanska analiza procesa struženja = [Analysis of plasticity applied to a problem of machining] : magisterij
Korošec, Marjan, 1961-
Do sedaj poznani postopki za določitev rezalnih sil temeljijo na klasični kinematiki nastajanja odrezka, ali na eksperimentalno dobljenih enačb. Naloga je pokazala, da je potrebno pri optimiranju ...odrezovalnega procesa upoštevati predvsem temperaturo, hitrost deformacije ter velikost utrditve v povezavi s parametri krivulje tečenja materiala. Krivulja tečenja materiala je konstruirana s pomočjo enostavnega tlačnega preizkusa ali pa na podlagi izmerjenih sil pri samem procesu ortogonalnega struženja. Vse veličine, določene na ta način, slučijo tudi pri optimiranju ostalih parametrov odrezavanja, ali pa kot vhodni podatki po nadaljnji natančnejši analizi procesa z metodo končnih elementov. Proces ortogonalnega struženja, ob pravilni predstavitvi plastomehanskih veličin predstavlja dober mehanski test za ugotavljanje fizikalno-mehanskih lastnosti normalno plastičnih materialov v področju visokih deformacijskih hitrosti, oziroma v adiabatnem področju.
