[ 1 ] - Resolution composite shell with a layer of piezoelectric vibration analysis
In this paper, the vibration of composite cylindrical shell with piezoelectric layers in the interior and exterior surfaces is investigated. The composite shell without piezoelectric layers can be studied and compared the results with the results of other researchers, the cylindrical shell laminated with layers of piezoelectric vibration checked. The result is a three-dimensional elasticity equ...
[ 2 ] - Severe Impact on the Behavior of Energy Absorbing Cylindrical Base in Frontal Impact
In this paper, the vibration characteristics of multi-layer shell that internal and external surfaces with a layer of piezoelectric sensor and actuator is investigated. The backrest shell laminated with simple analytical method to evaluate and the results were compared with results obtained by other researchers. The numerical solution methods (GDQ) for shells with piezoelectric layers and plain...
[ 3 ] - Elasticity Solution of Functionally Graded Carbon Nanotube Reinforced Composite Cylindrical Panel
Based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. In the process, stress and displacement fields are expanded according to the Fourier series along the axial and circumferential coordinates. From ...
[ 4 ] - بررسی رفتار دینامیکی و پایداری میکروتیرهای متحرک با خواص مدرج تابعی در جهت طولی
باهدف بهبود کارایی سامانه‌های متحرک محوری، ارتعاشات و پایداری میکروتیرهای رایلی مدرج محوری با حرکت طولی در این مقاله مطالعه شده است. همچنین، یک مطالعه پارامتریک مفصل برای توضیح اثر پارامترهای مختلف مانند درجه‌بندی محوری مواد، طول مشخصه ماده و اینرسی دورانی بر مرزهای پایداری تیرهای رایلی و اویلر-برنولی انجام شده است. فرض شده است که مشخصات مادی سیستم به‌طور پیوسته در راستای طولی به‌صورت خطی یا نم...
