Abstract AR
التشكيل الهوائي للسبائك اللاحديدة يستخدم بصورة واسعة إنتاج الأجزاء للتطبيقات التقليدية و المتقدمة.
لقد تم دراسة التشكيل اللدن لصفائح النحاس ذات النقاوة العالية تحت تأثير التشكيل لهوائي باستخدام القوالب المفتوحة و المغلقة.
و لقد تم تحديد منحنيات الخضوع بصورة عملية بالاعتماد على نظرية طاقة الانفعال.
أوضحت الدراسة بأن منحنيات الخضوع للقوالب المفتوحة تتمتد بصورة أكبر من التشكيل بالقوالب المغلقة.
بقينت مستويات الانفعال و توزيع الانفعالات بصورة منتظمة للصفائح المشكلة.
و لم يحصل أي تنحيف في مركز الصفائح المسحوبة.
Abstract EN
Pneumatic forming of nonferrous alloys is widely used to produce components for many traditional and advanced applications.
The plastic behaviours of high purity copper sheet were investigated under pneumatic forming using open and closed dies.
Experimental yield loci were determined based on the strain energy theory for open and closed dies.
It has been found that the yield loci in open die expanded more than that in close die.
The formability was improved due to reduction in friction coefficient.
The plane strain forming and the strain distribution remain mainly uniform throughout the drawing sheet.
The formed copper sheets were not thinned at the centre of the doom.
