Abstract
U ovom radu opisana je tehnologija oblikovanja metala deformiranjem te neki od utjecajnih parametra pri oblikovanju. Jedan od najčešće korištenih postupaka pri obradi limova je postupak savijanja. Značajniji problem prilikom procesa savijanja lima predstavlja elastični povrat. Također su opisani neki od faktora koji djeluju na pojavu i iznos elastičnog povrata. U eksperimentalnom dijelu rada proveden je postupak savijanja u tri točke za tri različita materijala. Tijekom eksperimentalne analize očitane su sile i elastični povrati, te je nakon toga provedena proračunska analiza. Usporedbom eksperimentalne i proračunske analize izvedeni su zaključci koji materijal podnosi najveću silu i ima najveći elastični povrat. Numeričkom analizom u programskom paketu MSC Marc Mentant SE pomoću metode konačnih elemenata, prikazana je raspodjela naprezanja i položaj neutralne linije.
Abstract (english)
In this thesis the deformation forming technology is described and some of the influential parameters in forming. One of the most commonly used processes in sheet metal processing is the bending process. A significant problem during the sheet metal bending process is the elastic springback. Some of the factors influencing the occurrence and amount of elastic springback are also described. In the experimental part of the thesis, a three - point bending procedure was performed for three different materials. During the experimental analysis, forces and elastic recovers were read, and a budget analysis was performed thereafter. By comparing experimental and computational analysis, conclusions were drawn as to which material withstands the greatest force and has the greatest elastic springback. Numerical analysis in the software package MSC Marc Mentant SE using the finite element method, shows the stress distribution and the position of the neutral line.
