چکیده

در این مقاله یک حل سه‌بعدی با فرمول­بندی ترکیبی لایه­گون جهت ورق‌های کامپوزیت لایه­ای با هندسه و شرایط مرزی دلخواه ارائه‌شده است. در این مطالعه میدان­های جابه‌جایی و تنش  خارج از صفحه به‌صورت مجموع یک سری توابع با ضرایب مجهول در نظر گرفته می­شوند. شرایط مرزی و پیوستگی جابه‌جایی­ها و تنش‌های بین لایه­ای در مرز لایه­های دقیقا ارضا می­شوند. معادلات تعادل و سازگاری، با استفاده از اصل تغییرات ریزنر اعمال می­شوند. نتایج نشان می­دهند که فرمول­بندی ترکیبی نسبت به فرمول­بندی جابه‌جایی دارای همگرایی سریع‌تری است و تنش‌های بین لایه­ای را با دقت بهتری ارائه می­کند.
