“…In this particular study, static deflections of cylindrical and spherical shaped pressurized tanks made of sandwich composites are investigated by using the higher order shear deformation theory. The effects of boundary conditions on the solution functions are introduced as described by Oktem and Chaudhuri [11] and the presented solution methodology is developed to apply to sandwich composites.…”

Liquefied gasses are defined as consisting of a broad range of petroleum gas mixtures, which, as listed in the rules of Turkish Lloyd [3], include: acetaldehyde, ammonia, butane, carbon dioxide, ethane, ethylene, nitrogen, refrigerant gasses, sulphur dioxide, etc. Liquefied gas transportation distinguishes three major gas conditions: (i) fully pressurized (pressurized at ambient temperature), (ii) semi-refrigerated (pressurized and refrigerated at optimum temperature and pressure), (iii) fully refrigerated (refrigerated at or near atmospheric pressure). The loads associated with these liquefied gas conditions are one of the main characteristics that determine the pressurized tank design. For refrigerated tanks, the tank material's lowtemperature toughness becomes the most important property to consider, since most materials become

“…Yukarıda (6a) eşitliğiyle tanımlanan sınır değer probleminin (7a,b) eşitliklerinde verilen sınır şartlarıyla çözümü klasik Navier ya da Levy metotlarıyla mümkün olmamaktadır [18,[21][22][23]. Bu nedenle yalnızca özel olarak tanımlanmış sınır koşulları için çözüme olanak sağlayan Navier ve Levy metotları dışında, herhangi bir sınır şartının çözümüne olanak sağlayan süreksiz Fourier serileri yaklaşımı çözüm olarak kullanılmıştır.…”

ÖZETSüreksiz Fourier serileri yöntemiyle fonksiyonel olarak derecelendirilmiş (FD) kompozit plakların statik analizi analitik bir çözüm tekniğiyle gerçekleştirilmiştir. Kısmi türevli yüksek dereceden lineer diferansiyel denklemlerin oluşturduğu sistem, ankastre ve basit mesnetli sınır şartları için süreksiz Fourier serileri yöntemiyle çözülmüştür. Plakın mekanik özelliklerinin kalınlık boyunca, bileşenlerin hacim oranları ölçüsünde üstel bir şekilde dağıldığı kabulü yapılmıştır. Analitik çözüm, sabit yayılı yük için, ticari bir sonlu elemanlar programı kullanılarak karşılaştırılmıştır. Sonuçların sonlu elemanlar çözümüyle elde edilenlerle yakın olduğu görülmüştür.Anahtar Kelimeler: Fonksiyonel kompozit, statik analiz, analitik çözüm, Fourier metodu STATIC ANALYSIS OF FUNCTIONALLY GRADED (FGM) COMPOSITE PLATES ABSTRACTStatic analysis of functionally graded (FGM) plates based on a higher order shear deformation theory is performed using an analytical solution technique. The boundary-discontinuous double Fourier series approach is used to solve a system of highly coupled linear partial differential equations with the mixed type clamped and simply supported boundary conditions prescribed at the edges. The mechanical properties of the plate are assumed to vary in the thickness direction according to a power-law distribution in terms of the volume fractions of the constituents. Analytical results are compared with finite element counterparts using commercially available software under uniformly distributed load. Present results are in good agreement with the finite element counterparts.

“…More recently, second-order and higherorder shear deformation theories (HSDTs), involving continuous in-plane displacements through the thickness of thick laminated plates, have appeared in the literature. A thorough and extensive review on the subject is available in work by Qatu et al [12] and Oktem and Chaudhuri [27]. In addition, theories and computational models based on equivalent single-layer, quasi-layerwise, and layerwise models have been developed for more precise calculations for laminated composite plates and sandwich shell structures [28,29].…”

A boundary-discontinuous generalized double Fourier-series-based solution to the problem of deformation of a finite-dimensional general cross-ply thick, doubly curved panel with negative Gaussian curvature and of rectangular planform, modeled using a higher-order shear deformation theory, is presented. This spectral method is used to solve a system of five highly coupled, linear partial differential equations, generated by the higher-order shear deformation theory-based laminated shell analysis, with the simply supported of type 2 boundary condition prescribed on two opposite edges, whereas the remaining two edges are subjected to the simply supported of type 3 constraint. The hitherto unavailable important numerical results presented include sensitivity of the predicted response quantities of interest to shell geometry (negative or positive Gaussian curvature), lamination and thickness effects, as well as their interactions.
