20.500.12556/DKUM-66565 Analysis of a strain rate field in cold formed material using the visioplasticity method Analiza polja brzine deformacije hladno deformiranog materijala rabljenjem vizioplastične metode In this paper the visioplasticity method is used to find the complete velocity and strain rate distributions from the experimental data, using the finite-difference method. The data about values of strain rates in plastic re- gion of the material is very important for calculating stresses and the prediction of product quality. Specimens of copper alloy were extruded with different lubricants and different coefficients of friction and then the strain rate distributions were analysed and compared. Significant differences in velocity and strain rate distributions were obtained in some regions at the exit of the deformed zone. U radu je primjenjena vizioplastična metoda za istraživanje raspodjele brzine i brzine deformacije iz eksperimentalnih podataka pomoću metode konačnih razlika. Rezultati brzine deformacije su vrlo značajni za računanje naprezanja unutar plastičnog područja, kao i za prognozu kvalitete proizvoda. Uzorci bakrene slitine bili su hladno istiskivani različitim mazivima s različitim koeficijentom trenja. U radu su analizirani i uspoređeni raspodjela brzina i brzina deformacije. Utvrđene su značajne razlike u raspodjeli brzine i brzine deformacije u području izlaska iz zone deformiranja. forward extrusion copper alloy visioplasticity strain rate lubrication istosmerno iztiskanje bakrene zlitine vizioplastičnost hitrost deformacije mazanje true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-03 11:21:01 2017-07-03 11:22:22 2022-08-01 12:55:17 2019-07-11 15:51:40 2009 0 0 str. 103-107 št. 2 Letn. 48 2009 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1334-2576 669.018.254:620.172.22=111 6892802 12988182 1334-2576 URN:SI:UM:DK:0IZEK8SR Metalurgija_2009_Gusel,_Rudolf,_Kosec_Analysis_of_a_Strain_Rate_Field_in_Cold_Formed_Material_Using_the_Visioplasticity_Method.pdf Metalurgija_2009_Gusel,_Rudolf,_Kosec_Analysis_of_a_Strain_Rate_Field_in_Cold_Formed_Material_Using_the_Visioplasticity_Method.pdf 1 BDBBC4BC31BAB241076976FBA74CFC40 3312b4b3c084e85414b4e25bd644f3113c2dd40c5b044d51a8bde7582a59f2b7 562eb49f-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/1ce2a49b-c364-4a64-8366-5a71ac54bb15 https://dk.um.si/Dokument.php?lang=slv&id=113477 http://hrcak.srce.hr/31997 1 https://dk.um.si/Dokument.php?lang=slv&id=113471 Fakulteta za strojništvo 0 0 0
