In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...

dehbid mylonite nappes associated with the tutak gneiss dome as the zagros hinterland involved-basement window in the zagros orogenic belt has significant components of dextral sense of shear along the mylonite nappes and are related to the high proportion of simple shear relative to pure shear deformation. kinematic vorticity analysis (wk) was made in order to determination of relative amounts...

Abstract In this study, the mechanical properties of composite plate were considered Gaussian random fields and their effects on buckling load corresponding mode shapes studied by developing a semi-analytical non-intrusive approach. The decomposed Karhunen—Loève method. strains defined based assumptions first-order higher-order shear-deformation theories. Stochastic equations motion extracted u...

Rotating fluid-filled shell structures can be used for different applications in technique. Because of spin-softening as well stress-stiffening it is essential to consider geometrical non-linearities. Additionally, shear deformation getting important case thick shells. At this point theories from KIRCHHOFF-LOVE (no deformation) and MINDLIN-REISSNER (first order are compared with each other. For...

in the present work, study of the vibration of a functionally graded (fg) cylindrical shell made up of stainless steel, zirconia, and nickel is presented. free vibration analysis is presented for fg cylindrical shells with simply supported-simply supported and clamped–clamped boundary condition based on temperature independent material properties. the equations of motion are derived by hamilton...

an important concern in rock mechanics is non-homogeneity as joints or fault. adopting the joints as fractures, fractures are well known for their effects on the mechanical and transport properties of rock. it has been postulated that through fractured/jointed rock, mainly, the polygons turned to the shear vector (ti) are involved in the mobilization of shear resistance. consequently, in order ...

A trigonometric plate theory is assessed for the static bending analysis of plates resting on Winkler elastic foundation. The theory considers the effects of transverse shear and normal strains. The theory accounts for realistic variation of the transverse shear stress through the thickness and satisfies the traction free conditions at the top and bottom surfaces of the plate without using shea...

This study investigates geometrical non-linear analysis of composite circular cylindrical shells under external pressure over part of their surfaces and also shells subjected to combined axial compression and triangular external pressure. Donnell non-linear shell theory along with first order shear deformation theory (FOSD) are adopted in the analysis. In the case of combined axial compression ...
