Effective wave propagation in a prestressed nonlinear elastic composite bar
The problem of determining the effective incremental response of nonlinearly elastic composite materials given some initial prestress is of interest in numerous application areas. In particular, the case when small-amplitude elastic waves pass through a prestressed inhomogeneous structure is of great importance. Of specific interest is how the initial finite deformation affects the microstructu...
متن کاملElastic–Plastic Wave Propagation in Uniform and Periodic Granular Chains
We investigate the properties of high-amplitude stress waves propagating through chains of elastic–plastic particles using experiments and simulations. We model the system after impact using discrete element method (DEM) with strain-rate dependent contact interactions. Experiments are performed on a Hopkinson bar coupled with a laser vibrometer. The bar excites chains of 50 identical particles ...
متن کاملWave Propagation in a Layer of Binary Mixture of Elastic Solids
This paper concentrates on the propagation of waves in a layer of binary mixture of elastic solids subjected to stress free boundaries. Secular equations for the layer corresponding to symmetric and antisymmetric wave modes are derived in completely separate terms. The amplitudes of displacement components and specific loss for both symmetric and antisymmetric modes are obtained. The effect of ...
متن کاملHigher-Order Splitting Method for Elastic Wave Propagation
Motivated by seismological problems, we have studied a fourth-order split scheme for the elastic wave equation. We split in the spatial directions and obtain locally one-dimensional systems to be solved. We have analyzed the new scheme and obtained results showing consistency and stability. We have used the split scheme to solve problems in two and three dimensions. We have also looked at the i...
متن کاملElastic-plastic Analysis of Jointed Rock Mass Using Meshless Method
Analysis of rock masses with plenty of weakness planes and joints with numerical methods based on meshes encounters difficulties. In the analysis when even only a few meshes are involved, mesh generation can consume more time and effort compared to the construction and solution of the discrete set of equations. Continuous remeshing of the domain in order to avoid the break down of the calculati...
