A Dual-Horizon Peridynamics–Discrete Element Method Framework for Efficient Short-Range Contact Mechanics

open access: yesModelling
Short-range forces enable peridynamics to simulate impact, yet it demands a computationally expensive contact search and includes no intrinsic damping.

Review of calibration strategies for discrete element model in quasi-static elastic deformation

open access: yesScientific Reports, 2023
This study first reviewed theories of the mechanical response of structures under loading, and the discrete element method provides a route for studying mechanical response including elastic deformation and structure failure.

Spectral element discretization of the Maxwell equations [PDF]

open access: yesMathematics of Computation, 1999
We consider a variational problem which is equivalent to the electromagnetism system with absorbing conditions on a part of the boundary, and we prove that it is well-posed. Next we propose a discretization relying on a finite difference scheme for the time variable and on spectral elements for the space variables, and we derive error estimates between

Slope Failure of Noncohesive Media Modelled with the Combined Finite–Discrete Element Method

open access: yesApplied Sciences, 2019
Slope failure behaviour of noncohesive media with the consideration of gravity and ground excitations is examined using the two-dimensional combined finite⁻discrete element method (FDEM).

Evaluating the Seismic Capacity of Dry-Joint Masonry Arch Structures via the Combined Finite-Discrete Element Method

open access: yesApplied Sciences, 2021
The behaviour of dry-joint masonry arch structures is highly nonlinear and discontinuous since they are composed of individual discrete blocks. These structures are vulnerable to seismic excitations.

Interfacing Finite Element and Boundary Element Discretizations

open access: yesApplied Mathematical Modelling, 1981
This paper reviews critically various implementation methods for coupling a mechanical finite element model to an infinite external acoustic domain discretized through boundary-element techniques. The associated physical problem is that of a three-dimensional structure submerged in an acoustic fluid, and impinged by a pressure shock wave.
