Moreover, a modified hardening model was proposed to capture the flow stress\u2013strain responses under various strain rates and temperatures with enhanced accuracy. Mechanical responses of the material were measured by using uniaxial tensile test at various temperature (\u224825\u2013250\u2009\u00b0C) and strain rates (\u22480.001\u20130.3\u2009s<jats:sup>\u22121<\/jats:sup>), and the split Hopkinson pressure bar (SHPB) test was also conducted to obtain flow behavior at the strain rate over 700\u2009s<jats:sup>\u22121<\/jats:sup> at room temperature. Based on these experimental data, two well accepted viscoplastic constitutive models\u2014Johnson\u2013Cook and Khan\u2013Huang\u2013Liang\u2014were evaluated. Finally, the Hollomon\/Voce type model was further developed, which resulted in significant improvement in predicting the flow stress curves under wide range of strain rate and temperature.<\/jats:p><\/jats:sec>","DOI":"10.1002\/srin.201500006","type":"journal-article","created":{"date-parts":[[2015,4,17]],"date-time":"2015-04-17T10:49:40Z","timestamp":1429267780000},"page":"902-914","source":"Crossref","is-referenced-by-count":3,"title":["Enhancement in the Modeling of Temperature and Strain Rate\u2010Dependent Plastic Hardening Behavior of a Sheet Metal"],"prefix":"10.1002","volume":"86","author":[{"given":"Dohyun","family":"Leem","sequence":"first","affiliation":[{"name":"Graduate Institute of Ferrous Technology POSTECH Pohang Gyeongbuk 790\u2010784 Korea"}]},{"given":"Hyuk\u2010Jong","family":"Bong","sequence":"additional","affiliation":[{"name":"Graduate Institute of Ferrous Technology POSTECH Pohang Gyeongbuk 790\u2010784 Korea"}]},{"given":"Frederic","family":"Barlat","sequence":"additional","affiliation":[{"name":"Graduate Institute of Ferrous Technology POSTECH Pohang Gyeongbuk 790\u2010784 Korea"}]},{"given":"Myoung\u2010Gyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Korea University Seoul 136\u2010701 Korea"}]},{"given":"Jung\u2010Han","family":"Song","sequence":"additional","affiliation":[{"name":"Incheon Institute of Industrial Technology KITECH Incheon 406\u2010840 Korea"}]},{"given":"Daeyong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Deformation KIMS Changwon 642\u2010010 Korea"}]}],"member":"311","published-online":{"date-parts":[[2015,4,17]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"393","volume":"381","author":"Maximov J.
