Using the infinitesimal theory of elasticity and analytical formulation, displacements and stresses based on the high-order shear deformation theory (HSDT) is presented for axisymmetric thick-walled cylinders made of functionally graded materials under internal and/or external uniform pressure. The material is assumed to be isotropic heterogeneous with constant Poisson’s ratio and radially varyi...
The article deals with modeling and calculations of volumetric machine-building structures complex geometry. relevance the work lies in fact that its methodology results can help design massive structural elements shape, including cylinders powerful hydraulic presses. Attention is paid to problems reducing metal content products safe conditions their operation. Theoretical applied based on nume...
In this study, the mechanical behaviours of thick-walled hollow functionally graded material (FGM) cylinder subjected to uniform pressures at inner and outer surfaces are proposed. The FGM has variable geometric profile, thickness properties like elastic modulus mass density all assumed vary radially according exponentially-varying functions in radial direction. With help infinitesimal elastici...
Polypropylene is one of the most common, fastest growing and versatile thermoplastics currently used to produce tanks and chemical piping systems. Even at room temperature creep is considerable for polypropylene products. The creep behavior of strains, stresses, and displacement rates is investigated in a thick-walled cylinder made of polypropylene reinforced by functionally graded (FG) multi-w...
