In this study, buckling analysis of panel types of marine and offshore structural components with initial imperfection under the combined action of lateral pressure and axial compression is carried out. The governing differential equations for thin and moderately thick shells are developed in terms of components of the displacement field. The governing ordinary differential equations are then d...

Abstract This paper investigates electro-magneto-elastic free vibration responses of piezomagnetic cylindrical nano panel subjected to electro-magneto-mechanical loads based on third-order theory. Third-order shell theory is used for description the displacement field. The zero transverse shear strains are obtained using Hamilton’s principle employed obtain governing equations motion. a couplin...

This study was conducted to address practical problems in producing structural pervious concrete, such as issues with mix proportioning, paste sagging, porosity, strength, and acoustic absorption. Concrete mixtures varying aggregate types, target void ratios, fiber contents were cast cylindrical panel-type specimens determine the compressive absorption coefficient. Porosities of concrete measur...

The failure mechanism of corrugated sandwich panels under three-point bending is investigated experimentally and numerically using ABAQUS/Standard. Three dominant modes failure, viz. face buckling, yielding core previously reported by others, were also identified here they found to be affected the face-sheet thickness, height corrugation angle panel. It will shown that deformation map, regime b...

Over the years, the ev8 code has been a very useful tool for the study of nuclear mean-field theory. Its main characteristic is that it solves the Hartree-Fock plus BCS equations for Skyrme type functionals via a discretization of the individual wave-functions on a three-dimensional cartesian mesh. This allows maximal flexibility in the determination of the nuclear shape by the variational proc...

In this paper, the nonlinear transient vibration of a cylindrical shallow panel under lateral white noise excitation is studied. The panel is in contact with a non aging viscoelastic medium. Since the external load is a time varying random wide band process, deterministic and conventional approaches cannot be used. Instead, the evolution of the probability density function of the response is in...

Accompanying the development of various highly technological materials, electronics and printing techniques advancing towards super-high precision and density, demands are progressively increasing for precisely automated visual inspections in their manufacturing processes. Despite these demands, inspections of printed patterns, sheet surfaces and semiconductors, in which defects on rather large...
