Wave Scattering From Infinite Cylindrical Obstacles of Arbitrary Cross-Section
… from an infinitely long cylindrical object of arbitrary cross-section. Due to the arbitrary geometry of the obstacle, a finite differences numerical method is employed to approximate the solution of the scattering problems. The wave equation is expressed in terms of generalized curvilinear …

The torsional analysis of beams of arbitrary cross-section with non-linear stress-strain properties
… the torsional capacity for prismatic beams with arbitrary cross-sections subjected to pure torsional loading. The technique may be applied to any beam with isotropic, homogeneous, linear or non-linear elastic properties and a known shearing stress–shearing strain relation. The theoretical …

Wave propagation in lossy waveguide structures
… and conductor losses in a guide having an arbitrary cross section and uses a full-wave solution process. A set of coupled, vector integral equations which characterize the system are derived. The equations enforce the necessary boundary conditions on the tangential electric and magnetic …

Estruturas tridimensionais com propriedades mecânicas dos materiais representadas matematicamente por séries - aplicação à análise de pontes
… curved, skew or retangular bridges with arbitrary cross section. The analysis allows the consideration of diaphragms. The mechanical properties are expanded into FOURIER series, allowing for variations in the material and geometric characteristics of the structure. Besides the mechanical …

Control of Dynamic Response of Thin-Walled Composite Beams Using Structural Tailoring and Piezoelectric Actuation
… structure is modeled as a thin-walled beam of arbitrary cross-section and incorporates a number of non-classical effects such as transverse shear, warping restraint, anisotropy of constituent materials and heterogeneity of the construction. Whereas structural tailoring uses the anisotropy …

Some properties of the magnetic response of mesoscopic superconducting rings
… criterion for a cylindrical geometry with arbitrary cross-section. We propose that the presence of a constriction i.e. thinning in the walls of the cylinder can substantially improve the stability of HQV. Results of Chapter 1 and partially Chapter 2 have been presented in the following …

Efficient inverse methods for supersonic and hypersonic body design, with low wave drag analysis
… tool for design of aerodynamic shapes of arbitrary cross section. These shapes can correspond to either "wing like" pressure distributions or to "body like" pressure distributions. Examples are presented illustrating the method for a non-axisymmetric fuselage type pressure distribution and …

Multiscale modelling of woven and knitted fabric membranes
… large deformations, rod-to-rod contacts, arbitrary cross-section de finitions and follower loads. Respecting the principle of separation of scales, we construct response databases by applying different homogenised strain states to the RVEs and recording the respective incremental …

Flows in Grooved Channels
… grooves have been considered which may have an arbitrary cross-section and an arbitrary orientation with respect to the flow direction. It has been shown that the grooves effects can be split into two parts; one due to the change in the mean positions of the walls and the other due to the flow …

Navier-Stokes prediction of the three dimensional flowfield of jets in a crossflow using the finite element method
… is generalized to account for the effect of arbitrary cross-section of the jets injected from a various nozzle configurations into a uniform crossflow. The model is implemented as a module of a general purpose finite-element computer code. The finite-element procedures used here follow from a …
