An embedded strong discontinuity model for cracking of plain concrete

TL;DR: In this article, a numerical model formulated within the framework of a nonsymmetric strong discontinuity approach for fracture simulations of plain concrete is presented, based on the fixed crack concept and makes use of the concept of the elements with embedded discontinuities.

Multiscale methods for mechanical science of complex materials: Bridging from quantum to stochastic multiresolution continuum

TL;DR: The bridging scale method (BSM) was originally proposed by Wagner and Liu as mentioned in this paper as an effective way of treating the interface in coupled atomistic/continuum simulation, which has become a very useful paradigm that has been applied to solve a host of problems in mechanical sciences of complex material systems.

On the numerical stability and mass-lumping schemes for explicit enriched meshfree methods

TL;DR: A group of problems that have attracted a great deal of attention from the EFG method community includes the treatment of large deformations and dealing with strong discontinuities such as cracks, one efficient solution to model cracks is adding special enrichment functions to the standard shape functions.

A finite element method for crack growth without remeshing

TL;DR: In this article, a displacement-based approximation is enriched near a crack by incorporating both discontinuous elds and the near tip asymptotic elds through a partition of unity method.

Element‐free Galerkin methods

TL;DR: In this article, an element-free Galerkin method which is applicable to arbitrary shapes but requires only nodal data is applied to elasticity and heat conduction problems, where moving least-squares interpolants are used to construct the trial and test functions for the variational principle.
