چکیده
Bu çalışmada; eksenel yönde fonksiyonel derecelenmiş malzemeli, doğru eksenli kolonların burkulma yükü Tamamlayıcı Fonksiyonlar Yöntemi (TFY) ile incelenmiştir. Burkulma davranışını idare eden birinci mertebeden kanonik denklemler, Euler-Bernoulli (BKT) ve Timoshenko kiriş teorilerine (TKT) dayalı olarak denge denklemleri yardımıyla elde edilmiştir. Adi diferansiyel denklem takımları, Python dilinde hazırlanan programla çözülmüştür. Malzeme değişim fonksiyonunun, uzunluk/kalınlık oranının farklı sınır koşullarının yüküne etkisi parametrik araştırılmıştır. Elde edilen yükleri, literatürde bulunan mevcut yöntemler Abaqus sonlu elemanlar programında değerler karşılaştırılmış, uygulanan yöntemin etkinliği gösterilmiştir.

Thermal Buckling Analysis of Functionally Graded Euler-Bernoulli Beams with Temperature-dependent Properties
Thermal buckling behavior of functionally graded Euler-Bernoulli beams in thermal conditions is investigated analytically. The beam with material and thermal properties dependent on the temperature and position is considered. Based on the transformed-section method, the functionally graded beam is considered as an equivalent homogeneous Euler-Bernoulli beam with an effective bending rigidity un...

The intention of this study is the analysis of thermal behavior of functionally graded beam (FGB). The distribution of material properties is imitated exponential function. For thermal loading the steady state of heat conduction with exponentially and hyperbolic variations through the thickness of FGB, is considered. With comparing of thermal behavior of both isotropic beam and FGB, it is appea...

In this paper, the buckling and vibration behaviour of functionally graded flexoelectric nanobeam is examined. The vibration and buckling formulations of functionally graded nanobeam are developed by using a new theory that’s presented exclusively for flexoelecteric nano-materials. So by considering Von-Karman strain and forming enthalpy equation based on displacement, polarization and electric...
متن کاملRelations between buckling loads of functionally graded Timoshenko and homogeneous Euler–Bernoulli beams
Analytical relations between the critical buckling load of a functionally graded material (FGM) Timoshenko beam and that of the corresponding homogeneous Euler–Bernoulli beam subjected to axial compressive load have been derived for clamped–clamped (C–C), simply supported–simply supported (S–S) and clamped–free (C–F) edges. However, no such relation is found for clamped–simply supported (C–S) b...
متن کاملAnalytic Approach to Free Vibration and Buckling Analysis of Functionally Graded Beams with Edge Cracks using four Engineering Beam Theories
A complete investigation on the free vibration and stability analysis of beams made of functionally graded materials (FGMs) containing open edge cracks utilizing four beam theories, Euler-Bernoulli, Rayleigh, shear and Timoshenko, is performed in this research. It is assumed that the material properties vary along the beam thickness exponentially and the cracked beam is modeled as two segments ...
