Some of the basic developments in the theory of electromagnetic field representation in terms of Hertz vectors are reviewed. A solution for the field in an inhomogeneous anisotropic medium is given in terms of the two Hertz vectors. Conditions for presentation of the field in terms of uncoupled transverse electric and transverse magnetic modes, in a general orthogonal coordinate system, are der...

Failure behavior of composite materials in general and particulate composites in particular is intimately linked to interactions between a matrix crack and a second phase inclusion. In this work, surface deformations are optically mapped in the vicinity of a crack–inclusion pair using moiré interferometry. Edge cracked epoxy beams, each with a symmetrically positioned cylindrical glass inclusio...

Localised pressure pulse loads can pose a significant threat to structural elements and critical equipment may cause failure damage in the target due concentrated energy delivered upon localised area of target. The impulse impinged local at contact interface exceed 80% total that charge deliver infinite target, leading potential perforation element. When multiple charges are detonated, advectio...

This study provides an approach to predict the springback phenomenon during post-solidification cooling in a functionally graded hybrid composite cylindrical shell with a transverse isotropic structure. Here, the material properties are given with a general parabolic power-law function. During the theoretical analysis, an appropriate transformation is introduced in the equilibrium equation, whi...

In this paper the turbulent flow in a cyclonic separator is investigated with large-eddy simulation (LES) based on a cylindrical coordinate spectral-element-Fourier method (SEM) using the Smagorinsky subgrid-scale model in its standard and dynamic formulation. The results show slight model differences, but both have poor agreement with measurements. The cylindrical-coordinate system geometry us...
