De la propagation à la diffusion des ondes dans les solides : apports et limites de la simulation numérique

Such physical parameters can be evaluated using Biot–Stoll model [3], [7], [8], [11], [32]. The Biot–Stoll model is widely used and a useful tool to analyze the acoustic

We present the algorithm of the RK4-IP method used for the purposes of the numerical study of the coherence properties of a fiber laser and we detail the embedded Runge-Kutta method

The class of stochastic non-gaussian positive-definite fields with minimal parame- terization proposed by Soize (Soize, 2006) to model the elasticity tensor field of a

L’objectif de ce mémoire est l’étude par simulation de la commande passive sur les systèmes électrotechnique avec une application sur le moteur dit asynchrone pour définir

For the case of a completely random distribution of particles in a matrix, however, we have presented mathematical rela- tions between the relevant parameters which describe

In this study, the process of wave propagation in weld joints including a flaw was simulated using elastic finite-difference time-domain (FDTD) method and a digitized

Then the exact upwind numerical fluxes developed in [17,18] are given before the presen- tation of the main result of the present work: the stability of the space dG method in

The measurement of matter radius is indeed a challenge, even for stable nuclei, the main default of the most used technique (total reaction cross section, elastic proton
