In conductive materials, Lorentz forces are only responsible for the ultrasounds transmitted by an EMAT (current limitation of <span class=\"g-color1\">CIVA<\/span> software). But <span class=\"g-color2\">some magnetization and magnetostriction effects have to be accounted for<\/span> when operating ferromagnetic materials inspection. Moreover, the impact of these various transduction mechanisms strongly <span class=\"g-color2\">depends on the EMAT design and on the ferromagnetic properties<\/span> of the inspected part. Thus, modeling such complex transduction effects is of paramount importance when designing an EMAT inspection, and <span class=\"g-color2\">this paper offers a generic model<\/span> that can be integrated into various numerical tools (such as <span class=\"g-color1\">CIVA<\/span> software) to help optimize EMAT design and give <span class=\"g-color2\">reliable data interpretation<\/span>.<\/p>\n<\/p>\n<p>If you are interested in this topic, impatient for such a model to be integrated in <span class=\"g-color1\">CIVA<\/span> software, or keen to share with us your experience \/ interest in EMAT inspection, please do not hesitate to <a class=\"lien\" href=\"https:\/\/www.extende.com\/contact\" target=\"_self\">contact us<\/a>!<\/p>\n<\/p>\n<p>The <span class=\"g-color1\">EXTENDE<\/span> team.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>You are interested in the use of EMAT probe for the ultrasonic inspection of ferromagnetic materials?
