The free vibration analysis of the functionally graded cylindrical shell panels  with and without cutout is carried out using the finite element method based on a higher-order shear deformation theory. A higher-order theory is used to properly account for transverse shear deformation. An eight noded degenerated isoparametric shell element with nine degrees of freedom at each node is considered....

This paper investigates the moments and stress resultants from infinite FG laminates with different polygonal cutouts subject to uniaxial tensile load. The analytical solution used for the calculation of stress resultants and moments is the basis of the complex-variable method and conformal mapping function. The impact of various factors, namely cutout orientation angle, cutout aspect ratio as ...

Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference (i.e., NAWF=5) indicates physiological cutout (Oosterhuis et al., 1999) may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project the overall objective of which is t...

Abstract Thermal buckling study on the symmetric laminated composite trapezoidal plate with a circular cutout subjected to uniform increase in temperature for various boundary conditions is explored this paper. In mathematical model, first-order shear deformation principle employed accordance variational energy system. For acquiring thermal temperature, nine-node heterosis relation has been use...

This work addresses a scheduling problem arising from an application in a real industrial context, namely task scheduling in the cutting department of a clothing industry. In general, clothes are produced by assembling fabric cutouts. In the cutting department, fabric rolls on a line with a constant speed, and is cut by automated machines arranged along the line. Machines are all identical. A f...

In dusty plasma experiments, the confining potential of the GEC rf Reference Cell is commonly assumed to be parabolic. There are various ways to test this assumption, many of which interfere with the plasma. We use the noninvasive method of perturbing a single particle suspended in the plasma with laser pulses. In this experiment a cw laser (532nm, 0.01.05W) supplied the radiation pressure forc...

A comparison of the buckling analysis of the nanoplate and nanocomposite plate with a central square hole embedded in the Winkler foundation is presented in this article. In order to enhance the mechanical properties of the nanoplate with a central cutout, the uniformly distributed carbon nanotubes (CNTs) are applied through the thickness direction. In order to define the shape function of the ...
