WebAug 1, 2024 · Two different strategies for discretization in dynamic analysis; (a) fixed non-uniform discretization, (b) adaptive refinement. Section 3.1 will address the first point, and Section 3.2 the second. 3.1. Coupling grids with different grid size The new method makes the coupling between any two peridynamic grids with different grid spacing possible. WebPeridynamics is a continuum mechanics formulation. In other words, we do not individually model atoms and molecules. If we use meshless scheme for numerical discretisation, the …
ADAPTIVE REFINEMENT AND MULTISCALE MODELING IN 2D PERIDYNAMICS
WebAdaptive mesh refinement (AMR) is also employed to properly capture disparate solution scales with a reduced number of grid points. The scheme is assessed in terms of discontinuity-capturing capabilities, spatial and angular solution accuracy, scalability, and serial performance through comparisons to other commonly employed solution techniques. WebApr 1, 2024 · A dual-horizon peridynamics (DH-PD) model is proposed for the simulation of debonding process in fiber-reinforced polymer (FRP)-to-concrete bonded joints. In the novel procedure of implementing DH-PD in the framework of finite element method (FEM), truss elements are employed to represent the bonds and dual-bonds. The quadtree approach is … lightweight fleece
