Suitable, yet general enough, choices of functional grading along the radius and thickness axisymmetric circular plates may lead to closed-form solutions for linear elastic direct problem. The are modeled according usual Kirchhoff—Love theory, because they supposed be thin; abstract from actual values geometric material parameters, governing equations dealt with in nondimensional form. Some ins...

Free bending vibration analysis of the functionally graded viscoelastic circular sandwich plates is accomplished in the present paper, for the first time. Furthermore, local shear corrections factors are presented that may consider simultaneous effects of the gradual variations of the material properties and the viscoelastic behaviors of the materials, for the first time. Moreover, in contrast ...

in order to lighten the prestressed concrete solid members, nowadays, it is possible to make use of the advantage of hpc (fc'>60 mpa) as well as replacing the solid section with a psc thin-walled section for certain members such as circular and box columns. using the strength theory of aci, a numerical procedure along with a computer program was developed for the analysis of such sections ...

Experimental Details: Materials Teflon (T) spheres (d T = 3.175 mm), Nylon-6,6 (N) spheres (d N = 3.175 mm), and sheets of aluminum (0.8 and 1.0 mm) were purchased from McMaster-Carr (Princeton, NJ). Circular frames were made by bending thin strips of aluminum (1.0 mm wide, 4–6 mm high, and 171–2 mm long) into circles of diameter 53.6 ± 0.2 mm. We glued the frames to square (75 mm) aluminum pla...

A new three node triangular plate element, labeled here as DST-S6 (Discrete Shear Triangular element with 6 extra Shear degrees of freedom), is proposed for the analyses of plate/shell structures comprising of thin or thick members. The formulation is based on the DKT (Discrete Kirchhoff Technique) and an appropriate use of the independent shear DOF(Degrees Of Freedom). The shear locking is com...

In this paper, several analyses were conducted to investigate the buckling behavior of Functionally Graded Material (FGM) thin plates with various circular cutout arrangements. The computer model was simulated using Finite Element (FE) software ABAQUS. developed validated by authors in previous research. A parametric analysis employed effect plate thickness and diameter on FGM plates. normalize...

In this paper, the degenerate scale for plate problem is studied. For the continuous model, we use the null-field integral equation, Fourier series and the series expansion in terms of degenerate kernel for fundamental solutions to examine the solvability of BIEM for circular thin plates. Any two of the four boundary integral equations in the plate formulation may be chosen. For the discrete mo...

Piezoelectric bimorph actuation has been successfully used in numerous types of microdevices, most notably micropumps. However, even for the simple case of circular geometry, analytical treatments are severely limited. This study utilized the finite-element method to optimize the deflection of a circular bimorph consisting of a single piezoelectric actuator, bonding material and elastic plate o...
