Abstract: As a common composite site, the hill-canyon topography has complex coherence effects on seismic wave scattering. However, the publications of related research are still very limited. Therefore, a multi-domain indirect boundary element method was proposed to solve the scattering of in-plane elastic w...
Abstract: The heat conduction is a common problem in engineering practice. Compared with those of isotropic materials, the heat conduction problem of anisotropic materials is more complicated, so it is of great significance to accurately predict the internal temperature distribution. The numerical manifold me...
Abstract: To simplify the 3D finite element modeling process for composite box girders with corrugated steel webs, the finite element model for 3D corrugated steel webs was reduced to one for 2D orthotropic plates with the equivalent stiffness and displacement method. The simplified finite element model has a...
Abstract: The dynamic responses of 3D, 2D and 1D track-ground models under moving loads were analyzed based on the Fourier transformation technique. The track was modelled as a Timoshenko beam, and response discrepancies between the 3 models were compared in terms of different load speeds and ground thickness...
Abstract: Based on the 2D fluid-structure coupling theory, the wind-induced vibration responses of transmission lines across 2 close hills were calculated. Both the load on the wire by the mountain wind and the surface wind pressure change caused by wire vibration with its influence on the flow field were con...
Abstract: Based on the smooth particle hydrodynamics (SPH) method, the stability of the tank truck and the mitigating effects of different baffles were studied. Firstly, the liquid sloshing pressure in a rectangular container was simulated with results in agreement with experimental ones, to validate the effe...
Abstract: The diversion of a meandering river made the properties of sedimentary reservoir distribute along the direction of channel extension. The conventional geostatistics method depends on the range and direction of the variogram in the prediction of reservoir parameters. According to the basic principle ...
Abstract: The Riccati-Bernoulli auxiliary equation method was proposed to seek the exact travelling solutions to the generalized nonlinear Schrodinger equation and the (2+1)-dimensional nonlinear Ginzburg-Landau equation. The solutions can be expressed with the rational functions, the trigonometric functions,...
Abstract: Rotavirus is the leading cause of severe diarrhea in children worldwide. To study the spread of rotavirus, a rotavirus transmission model was proposed based on the characteristics of temporary immunity after infection and maternal antibody protecting the newborn. By means of dynamic analysis, the ba...
Abstract: The wave model generated for laser plasma was discussed, which can be expressed as the Riemann problem of Burgers equations with initial value discontinuity. The singularly perturbed asymptotic solution of the Burgers equations with discontinuous initial values was obtained with the singularly pertu...
