en موتور احتراق داخلی Internal Combustion Engines (ICE, ...) پژوهشي Research In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset and growth of defects (e.g., bursting and wrinkling) and to promptly readjust the loading paths. Thus, a suitable load path is determined by applying Adaptive Simulation Method in ANSYS Parametric Design Language (APDL). forming, finite element simulation, bursting 555 563 http://ase.iust.ac.ir/browse.php?a_code=A-10-63-54&slc_lang=en&sid=1 Masoumi Khalil Abad 18003194753284600967 18003194753284600967 Yes Ghazanfari 18003194753284600968 18003194753284600968 No Hashemi 18003194753284600969 18003194753284600969 No
