Here, the Downhill-Simplex-Algorithm is applied to the inverse determination of Johnson-Cook material model parameters for the Aluminum alloy Al 6060. For this purpose, orthogonal cutting experiment were conducted to set the experimental database for the inverse determination. Following, iterative FE-simulations were conducted in order to determine the material model parameters. The results of the inverse determination showed to result in a good agreement between simulated and experimental results within a small number of iterations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords<\/strong>: Material model, Johnson-Cook, Inverse determination, Finite element simulation<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Video presentation<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"http:\/\/cirpicme.org\/wp-content\/uploads\/2021\/07\/Marvin_Hardt.mp4\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Presenting author<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-subtle-light-gray-background-color has-background\"><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><tr><td><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" class=\"wp-image-2242\" style=\"width: 150px;\" src=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/DSC_4972_1_square.jpg?resize=150%2C150\" alt=\"\" srcset=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/DSC_4972_1_square.jpg?w=1008&amp;ssl=1 1008w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/DSC_4972_1_square.jpg?resize=300%2C300&amp;ssl=1 300w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/DSC_4972_1_square.jpg?resize=150%2C150&amp;ssl=1 150w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/DSC_4972_1_square.jpg?resize=768%2C768&amp;ssl=1 768w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/td><td><strong>Name:<\/strong><br><br><strong>Affiliation:<\/strong><br><br><strong>Email:<\/strong><\/td><td>Marvin Hardt<br><br>WZL of RWTH Aachen University, Germany<br><br>m.hardt@wzl.rwth-aachen.de<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Marvin Hardt, Thomas Bergs (Germany) Abstract Modeling the material behavior under metal cutting conditions is a prerequisite for the successful simulation of the cutting process by means of Finite Element (FE) simulations.
