Open AccessA semi-Lagrangian reproducing kernel particle method with particle-based shock algorithm for explosive welding simulation
The explosive welding process is an extreme-deformation problem that involves shock waves, large plastic deformation, and fragmentation around the collision point, which are extremely challenging features to m...

Open AccessA variational multiscale immersed meshfree method for heterogeneous materials
We introduce an immersed meshfree formulation for modeling heterogeneous materials with flexible non-body-fitted discretizations, approximations, and quadrature rules. The interfacial compatibility condition i...

Stabilized and variationally consistent nodal integration for meshfree modeling of impact problems
Galerkin meshfree methods can suffer from instability and suboptimal convergence if the issue of quadrature is not properly addressed. The instability due to quadrature is further magnified in high strain rate...

Open AccessAn iterative asymptotic expansion method for elliptic eigenvalue problems with oscillating coefficients
In this work we propose a method for obtaining fine-scale eigensolution based on the coarse-scale eigensolution in elliptic eigenvalue problems with oscillating coefficient. This is achieved by introducing a 2...
