Računalniško simuliranje postopka kovanja
Janez Stupan, Iztok Potrč, 2000, professional article

Abstract: V prispevku je obravnavano tridimenzionalno računalniško simuliranje procesa kovanja z računalniškim programom MSC/SuperForge. Kovanje je izrazit proces tridimenzionalne deformacije, med katerim se stalno spreminjajo robni pogoji. Začetna oblika je v večini primerov preprosta, končna oblika pa je lahko zelo zahtevna in se doseže s preoblikovanjem v več stopnjah. Rezultati simuliranja so: deformirana oblika, temperaturno polje, polje toka materiala, tlaka, dejanske napetosti, dejanskih plastičnih deformacij itn.

Computer-aided analysis of the forging process
Matjaž Šraml, Janez Stupan, Iztok Potrč, Janez Kramberger, 2004, original scientific article

Abstract: This paper presents computer simulation of the forging process using the finite volume method (FVM). The process of forging is highly non-linear, where both large deformations and continuously changing boundary conditions occur. In most practical cases, the initial billet shape is relatively simple, but the final shape of the end product is often geometrically complex, to the extent that it is commonly obtained using multiple forming stages. Examples of the numerical simulation of the forged pieces provided were created using Msc/SuperForge computer code. The main results of the analysis are deformed shape, temperature, pressure, effective plastic strain, effective stress and forces acting on the die.
