چکیده
با استفاده از روش نوارمحدود نیمه‌تحلیلی، کمانش و پس‌کمانش صفحات کامپوزیتی لایه‌ای تقویت شده با آلیاژهای حافظه‌دار که تحت بارگذاری حرارتی یکنواخت قرار دارند، بررسی می‌شود. هدف اصلی بررسی تاثیر قرارگیری الیاف حافظه‌دار در رفتار صفحه می‌باشد. در روش نوارمحدود به‌دلیل اعمال توابع مثلثاتی می­توان انتگرال انرژی را به‌صورت تحلیلی محاسبه کرد. تئوری تغییر شکل جابه‌جایی زیگ-زاگ لایروایز همراه با روابط سازگاری غیرخطی فون کارمن اجرا شده است. روش حل بر اساس به حداقل رساندن انرژی پتانسیل کل و حل مسئله مقدار ویژه یا مجموعه‌ای از معادلات غیر­خطی با استفاده از روش نیوتن-رافسون تکراری-افزایشی است. با استفاده از مدل برینسون ساده شده یک بعدی، تأثیر الیاف حافظه­دار (اثرات پیش­کرنش در نسبت­های حجمی مختلف) بر کمانش و پس­کمانش صفحات کامپوزیتی مورد بررسی قرار می‌گیرد. با استناد به کارهای دیگران و مطالعات پیشین روش نوار محدود به درستی اعمال گردیده است و نتایج مهمی به‌دست آمده­است.

چکیده English

Using the semi-analytical finite strip method, this study investigates the buckling and postbuckling behavior of laminated composite plates embedded with shape memory alloy (SMA) fibers under uniform thermal loading. The primary objective is to examine the influence of SMA fiber placement on the structural response of the plate. The finite strip method employs trigonometric functions, allowing the energy integral to be evaluated analytically. The zig-zag displacement deformation theory, based on Reddy’s layerwise approach, is implemented in conjunction with the nonlinear von Kármán compatibility relations. The solution methodology relies on minimizing the total potential energy and solving either an eigenvalue problem or a system of nonlinear equations using the incremental-iterative Newton–Raphson method. By adopting a simplified one-dimensional Brinson model, the effects of SMA fibers including pre-strain at various volume fractions on the buckling and postbuckling behavior of composite plates are thoroughly analyzed. Drawing on previous research and existing literature, the finite strip method is applied accurately, and significant findings are obtained.
