Assessment of assembly shape and geometric effects on amplification of shear waves using discrete element method
文献摘要：
The discrete element method(DEM)is a capable tool used to simulate shear wave propagation in granular assemblies for many years.Researchers have studied assembly shapes such as rectangles(in 2D simula-tions)or cylinders and cubes(in 3D simulations).This paper aimed to qualify the effect of assembly shape on the shear wave propagation and maximum amplification in the vertical plane(horizontal and vertical directions)caused by this propagation.To this end,shear wave propagations in different assembly shapes such as rectangle,trapezium,and triangle with rigid boundary conditions were simulated.A sine wave pulse was applied with a point source by moving a particle as the transmitter particle.To evaluate the shear wave velocity of the assemblies,the transmitter and receiver particles were simulated.All the sim-ulations were performed with 2D DEM which is a useful tool to determine the amount and location of the maximum amplification factor of the assembly in both horizontal and vertical directions.An advantage of this study was assessing the effect of parameters such as input wave frequency,assembly height,shape,and aspect ratios on the amplification of the input waves.
