Računalniško simuliranje procesov toplotne obdelave podevtektoidnega jekla z diodnim laserjem : doktorsko delo

Bojinović, Marko

V disertaciji je predstavljen numerični model in validirana računalniška simulacija laserske toplotne obdelave podevtektoidnega jekla 50CrV4. Za numerično reševanje matematičnega modela je ... uporabljena metoda končnih elementov v komercialnem programskem paketu ABAQUS nadgrajenim z lastnimi podprogrami. Računalniška simulacija je validirana v treh soodvisnih sklopih, to je validacija temperaturnega polja na površini obdelovanca, validacija trdote po globini obdelovanca in validacija spremembe geometrije obdelovanca. S pomočjo validirane računalniške simulacije je prikazan vpliv tehnoloških parametrov pri laserskih toplotnih obdelavah na temperaturno polje, trdoto ter deformacijsko-napetostno polje na obdelovancu v obliki kvadra velikosti 100 x 100 x 15 mm. V delu je še posebej predstavljen vpliv hitrosti segrevanja in vpliv začetne mikrostrukture na kinetiko faznih transformacij in trdote pri laserski toplotni obdelavi podevtektoidnega jekla.
