This article presents a new analysis of the vibration characteristics open-edge cracks for graded moving beams under thermal load. The material property gradient is based on distribution power law in direction beam thickness. equation obtained depending precept Hamilton and resolved by extension Galerkin’s approach. A rotational spring used to represent cracking beam. effects axial velocity, in...

Functionally graded materials are commonly used in thermal environment to change the properties of constituent materials. The new numerical procedure of functionally graded skew plates in thermal environment is presented in this study based on the C0-form of the novel third-order shear deformation theory. Without the shear correction factor, this theory is also taking the desirable properties a...

In this paper, the modified couple stress theory is used to study vibration analysis of functionally graded rectangular micro-plates. Considering classical and first order plate theories, the couple governing equations of motion are obtained by using the Hamilton’s principle. Considering an assumed mode method, the accurate size dependent natural frequencies are established for simply supported...

Safety analysis has been done for the torsion of a functionally graded thick-walled  circular cylinder under internal and external pressure subjected to thermal loading. In order to determine stresses the concept of Seth’s transition theory based on generalized principal strain measure has been used. This theory simplifies the set of mechanical equations by mentioning the order of the measure of...

The aim of this paper is to compare the static deflections and stress results of layered and functionally graded composite beams under static load. In the comparison study, the results obtained for a cantilever beam under point load. The Timoshenko beam and the Euler-Bernoulli beam theories are used in the beam model. The energy based Ritz method is used for the solution of the problem and alge...

The work applies topology optimisation to the design of functionally graded materials (FGMs) and materialinterfaces for thermomechanical problems. It is well known, that the mismatch in stiffness and thermal expansioncoefficient of two materials give rise to high stresses at the interface. One way to alleviate this is to use the conceptof FGMs [1]. The FGMs are here designed using t...

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 di...
