Stiffness matrix method for modelling wave propagation in arbitrary multilayers

Seismic Wave-Field Propagation Modelling using the Euler Method

Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy. It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. Moreover, the main drawbacks of the finite difference method are the low level of accuracy and the numerical dispersion for l...

Computer Modelling Wave Propagation

 In recent years the application of computer algebra systems devoted to Mathematics and Physics have become very popular both in instruction and scientific research. In this paper some issues arising in solving and modelling mathematical and physical problems in wave propagation will be discussed. In particular, computer algebra systems make easy to provide at the same time a large amount of d...

Wave Propagation Modelling for Inter-vehiclecommunications

A new model to analyse the wave propagation between moving vehicles is presented in this paper. The approach consists of tree major parts: the modelling of the road traffic, the modelling of the environment adjacent to the road lane and the actual modelling of the wave propagation. A realistic traffic model is used to generate time series of instantaneous positions and velocities of vehicles on...

A Potential Method for Body and Surface Wave Propagation in Transversely Isotropic Half- and Full-Spaces

The problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. Using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...
