Image solution for Poisson's equation in wedge geometry

IEEE Transactions on Antennas and Propagation, 1995
The Poisson's equation for a dielectric wedge is solved by deriving a static image that corresponds to the potential contribution of the wedge. The problem is studied mainly in three dimensions but the solution for the analog two-dimensional problem is also provided.

Stress intensity factors for wedge-splitting geometry

International Journal of Fracture, 1996
The wedge-splitting test is a novel procedure for measuring fracture properties in quasi-brittle materials, such as ceramics, rocks and concrete. Stress intensity factors, for most of the practical wedge-splitting geometries, have been computed and are presented in this paper in analytical and graphical form.

Geometry of Arrested Thermal Wedges

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1989
The geometry of arrested thermal wedges is studied on the basis of Schijf and Schoenfeld’s one-dimensional model. The derived equations for the dimensionless length and shape of the wedge are also given in graphic form in terms of the Darcy-Weisbach interfacial-friction coefficient, \If\di\N, and easily measured gross flow and density parameters ...

Effect of the shadow geometry in wedge diffraction

Journal of the Optical Society of America A, 2009
The surface integrals of the modified theory of physical optics are divided into two parts for diffraction by a wedge. Each integral represents the incident or reflected field scattered by one of the faces of the wedge. The results are investigated numerically and compared with the uniform theory of diffraction.

Using Geometry for the Dorsiflexory Wedge Osteotomy of the First Metatarsal

The Journal of Foot and Ankle Surgery, 2014
Dorsiflexory wedge osteotomy is indicated for the correction of structural and irreducible first metatarsal deformity to effectively shorten and elevate a plantar flexed first ray. This is most commonly due to fixed forefoot valgus deformity, the cavovarus foot type, and diabetic foot pathologic features involving an ulceration or preulcerative area on

Modelling the geometry of Coulomb thrust wedges

Journal of Structural Geology, 1988
Abstract Internal geometry and detachment of Coulomb thrust wedges is examined in a combined gravity and pressure force field under various boundary conditions and Coulomb parameters. Frontally buttressed sand wedges accreted with narrow tapers above soles with negligible friction. In these models, serial imbricates stepped-up in conjugate sets which

Embedding formulae for diffraction by rational wedge and angular geometries

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005
Embedding is the process of taking the far-field directivity from a diffraction problem (or problems) involving line sources or multipoles placed at a sharp edge, and then constructing the far field, for the same geometry, for more general incidence using only this canonical problem(s).

Numerical study of shock interactions on double-wedge geometries

34th Aerospace Sciences Meeting and Exhibit, 1996
Steady shock interactions in perfect gas flows over double-wedge geometries are studied using computational fluid dynamics. In inviscid flow four possible steady shock interactions are observed. These are the standard Type IV, V, and VI, as well as an apparent new interaction.

Combined forced and natural convection flow for the wedge geometry

International Journal of Heat and Mass Transfer, 1965
Abstract This paper considers simultaneously the phenomena of forced and natural flow effects over an isothermal wedge. The analysis is restricted to situations in which the natural convection effects may be considered as a perturbation of the purely forced flow situation.

Enumerative geometry, topological recursion, and the semi-infinite wedge

2022
Recent decades have seen an explosion of activity in the symbiotic relationship between mathematics and physics. From this interplay has emerged the notion of topological recursion, a general theory that appears to govern seemingly disparate problems in geometry, algebra, and mathematical physics.
