Formability enhancement of DP600 steel sheets in electro

Jun 01, 2017· Therefore EHFF conditions do not lead to any significant increase in formability in DP600 and AA5182 O sheet materials. In this paper, the increase in formability in EHF will be quantified by comparing the strains attained in electrohydraulic die forming (EHDF) experiments with the conventional FLC for a DP600 dual phase steel taking into account the effect of non linear strain paths.Formability enhancement of DP600 steel sheets in electro The formability of DP600 steel sheets improved by more than 60% under EHDF in biaxial stretching and by more than 120% under EHDF in plane strain compared with quasi static forming [11]. Forming limit diagram of DP600 steel sheets during The results showed that the maximum equi biaxial stretching forming limit was obtained at the optimal wire length of 45 mm and lifting height of 37 mm, then the entire FLC was generated to evaluate the formability of DP600 steel sheets with these optimal parametersa relative increase of 17.570% in major strain obtained by EHF was observed in all three regions of the FLC (tension tension, plane

Hyperplasticity mechanism in DP600 sheets during

The preliminary investigations discussed in Section 2 of this paper concluded that a high strain rate EHF process can enhance the formability of DP600 steel sheets, and the deformed specimens showed a characteristic of hyperplasticity. Therefore, this section will discuss the mechanisms of hyperplasticity that occurred during the EHF process from the macro scale and micro scale perspectives.Hyperplasticity mechanism in DP600 sheets during The objectives of this paper are to quantify the increase in formability of DP600 steel sheets in electrohydraulic die forming (EHDF). The conventional (quasi static) and high strain rate formingInfluence of wire parameters on the formability of DP600 The acoustic pulses caused by the underwater wire explosion can be used to apply work on the surrounding medium. This work designed a set of adjustable wire explosion impact forming tooling to investigate the influence of wire parameters on the formability of DP600 steel sheets.

Hyperplasticity mechanism in DP600 sheets during

Further, Cheng et al. (2017) analyzed the die effects on the formability of DP600 steel sheets during an EHF process and showed that the limit strains were increased by 60 % in a biaxial tension strain path and by 120 % in a plane strain path. Therefore, these investigations indicated that the die was beneficial to the improvement in Forming limit diagram of DP600 steel sheets during Cheng J, Green DE, Golovashchenko SF (2017) Formability enhancement of DP600 steel sheets in electro hydraulic die forming.
