Removing scattering e ects of rugged topography using nite di erence method
نویسندگان
چکیده
A method based on w ave-equation nitedi erence algorithm with irregular free surface is introduced to remove the scattering e ects of rugged topography. The anomalies and multiples caused by the irregular surface and shallow layers of inhomogenous media are removed before further processing steps. Simple conformal elements of nite di erence are adopted to model the irregular surface. Randomness of media of the shallow layers is considered. Numerical tests presented in the paper show the e ectiveness of the method.

A review is made on the dierent methods used for the estimation of transverse/interlaminar stresses in laminated composite plates and shells. Both analytical and numerical methods are considered. In numerical methods while the emphasis is given on ®nite element methods, other methods like the ®nite dierence method is also brie ̄y discussed. Aspects considered are: eects of variation in geomet...
متن کاملVoronoi cell nite di erence method for the di usion operator on arbitrary unstructured grids
Voronoi cells and the notion of natural neighbours are used to develop a nite di erence method for the di usion operator on arbitrary unstructured grids. Natural neighbours are based on the Voronoi diagram, which partitions space into closest-point regions. The Sibson and the Laplace (non-Sibsonian) interpolants which are based on natural neighbours have shown promise within a Galerkin framewor...

متن کاملA continuum sensitivity method for nite thermo-inelastic deformations with applications to the design of hot forming processes
A computational framework is presented to evaluate the shape as well as non-shape (parameter) sensitivity of nite thermo-inelastic deformations using the continuum sensitivity method (CSM). Weak sensitivity equations are developed for the large thermo-mechanical deformation of hyperelastic thermoviscoplastic materials that are consistent with the kinematic, constitutive, contact and thermal ana...
متن کاملMulti Domain WENO Finite Di erence Method with Interpolation at Sub-domain Interfaces
ABSTRACT High order nite di erence WENO methods have the advantage of simpler coding and smaller computational cost for multi-dimensional problems, compared with nite volume WENO methods of the same order of accuracy. However a main restriction is that conservative nite di erence methods of third and higher order of accuracy can only be used on uniform rectangular or smooth curvilinear meshes. ...
