Contour plots of concentration in a 3D corrosion problem

Efficient and accurate calculation of spatial integrals is of major interest in the numerical implementation of peridynamics. The standard way to perform this calculation is a particle-based approach…

The four symmetry groups (up to a change in orientation) of the elasticity tensor in 2D.

We present an elementary and self-contained proof that there are exactly four symmetry classes of the elasticity tensor in two dimensions: oblique, rectangular, square, and isotropic. In two…

Hat shape three-point bending test simulation

To predict the mixed damage modes of unidirectional fiber-reinforced polymer (FRP) laminates under dynamic loading, a finite element method (FEM) based peridynamic model is introduced in this work.…

Largest connected component of the 2019 peridynamics co-authorship network

Peridynamics is a relatively new field in continuum mechanics that has developed over the past 20 years. This work studies the evolution of collaborations in the field of peridynamics since its…

Distribution of displacement gradients in a three-point bending test. High gradients are concentrated around the applied load point (top center) as well as at the supports (bottom left and right) and at the crack tip (bottom center).

Coupling peridynamics based computational tools with those using classical continuum mechanics can be very beneficial, because it can provide a means to generate a computational method that combines…

Novel anisotropic peridynamic kernels. Left:  plane strain peridynamic kernel derived from a 3D cubic material model. Right: 2D peridynamic kernel for a square material model.

This paper concerns anisotropic two-dimensional and planar elasticity models within the frameworks of classical linear elasticity and the bond-based peridynamic theory of solid mechanics. We begin by…

This paper explores the restrictions imposed by bond-based peridynamics, particularly with respect to plane strain and plane stress models. We begin with a review of the derivations in [1] wherein…

Concentration evolution in a metallic corrosion problem. Top: reference solution. Bottom: solution with the proposed absorbing boundary conditions

Diffusion-type problems in (nearly) unbounded domains play important roles in various fields of fluid dynamics, biology, and materials science. The aim of this paper is to construct accurate…

Analytical and peridynamic (PD) saturation profiles.

A general state-based peridynamics model is developed to simulate transport of fluids in an arbitrary heterogeneous porous medium. The generality encompasses modeling of multiphase,…

Overview of classes of LtN coupling approaches and corresponding methods

Local-to-Nonlocal (LtN) coupling refers to a class of methods aimed at combining nonlocal and local modeling descriptions of a given system into a unified coupled representation. This allows to…
