Deep Drawability of 5083 Al-Mg Alloy Sheet at Elevated Temperature and its Prediction

A study on the analytical modeling for warm hydro-mechanical deep drawing of lightweight materials

“…In Naka's experiment, hydraulic pressure was not applied while the flange area and the punch area were kept at 180 and 25 1C each. Other conditions and material properties were adopted from Naka's reports [9,25]. The LDR values predicted from analytic model matched well with the experimental results and FEA results.…”

“…The analytical model was also compared with another set of experimental and analytical results by Naka [9,25] as shown in Fig. 13.…”

“…For warm forming conditions, Naka et al [9] developed a simple analytical model for warm deep drawing using temperature and strain rate dependent material properties of an aluminum alloy. They did not consider the thickness change of the sheet and plastic bending effect in the analysis.…”

Development of an analytical model for warm deep drawing of aluminum alloys

“…In this study, in order to develop guidelines and extend the fundamental understanding of warm forming process, an attempt has been made to develop an analytical model considering a simple circular cup part based on the previous investigations reported in the literature (Chung and Swift, 1952a;Yamada, 1961;Chang and Wang, 1998;Naka et al, 2000). All effects of tooling geometry, anisotropy, friction, and blank holder pressure (BHP) were included in the model, and the material parameters for hardening constants dependent on temperature and strain rate were implemented to describe the warm forming conditions.…”

“…Naka et al (2000) developed a simple analytical model for warm deep drawing using temperature and strain rate dependent material properties of an aluminum alloy without considering the thickness change of the sheet and plastic bending effect. They reported that the predicted drawing ability of cylindrical cups was in good agreement with the corresponding experimental results.…”
