چکیده

در این مطالعه، پاسخ غیرخطی نانوکامپوزیت‌های گرافنی نسبت به تشدید هارمونیک بررسی شده است. از اهداف این مقاله ارایه روابط دینامیکی مواد نانو‌کامپوزیتی است که در آن اثرات هم‌زمان غیرخطی‌های هندسی و میرایی انرژی ناشی از محیط ویسکوالاستیک خارجی و میرایی داخلی در نظر گرفته شده است. بر اساس نظریه الاستیک غیرموضعی، روابط غیرخطی کرنش- جابه‌جایی وون- کارمن، معادله اساسی حرکت غیرخطی با روش همیلتون به‌دست آمده است و سپس با استفاده از روش گالرکین، به یک معادله دیفرانسیل معمولی غیرخطی ساده‌سازی می‌شود. این معادله برای یافتن رابطه فرم بسته بین فرکانس- دامنه ارتعاش ورق گرافنی چهارسر تکیه‌گاه ساده به‌صورت تحلیلی به‌وسیله روش مقیاس‌های چندگانه حل می‌شود. مطالعه پارامتری هم به‌صورت ویژه بر مجموعه‌ای از عوامل هم‌چون پارامتر غیرموضعی، نسبت ابعادی و هر دو ضریب میرایی (داخلی و خارجی) و نیز فرکانس نیروی تحریک خارجی انجام شده است. نتایج به‌دست آمده اثرات سختی افزایی غیرخطی را در حالت تشدید اولیه و همچنین پدیده‌های قابل توجه دیگری را برخلاف تحلیل خطی نشان می‌دهد.

چکیده [English]

In this study, the nonlinear responses of graphene-based nanocomposite to harmonic resonances have been discussed. This paper presents results of a study aimed at representing dynamic interactions in nanocomposite with simultaneous consideration of geometrical nonlinearity and energy damping effect by viscoelastic medium and internal damping. Based on nonlocal elasticity theory and invoking the nonlinear von Karman strain- displacement relations, the nonlinear governing equation is extracted using the Hamilton principle. To reduce the equation of motion to a nonlinear ordinary differential equation, the Galerkin’s procedure is implemented; then using the multiple scale method, the obtained equation is solved analytically to assess the closed form nonlinear amplitude-frequency relations relevant to graphene with simply supported boundary conditions under harmonic excitation. The detailed parametric study is conducted, focusing on the series effects of nonlocal parameter, aspect ratio and both damping coefficients (internal and external), and frequency of excitation load. The outcomes show a hardening nonlinearity effect for the primary resonance as well as illustrate some phenomena different from the linear vibration
