The space-splitting idea combined with local radial basis function meshless approach to simulate conservation laws equations

Alexandria Engineering Journal, 2018
One acceptable technique in meshfree methods is collocation procedure based on the radial basis functions. But the mentioned technique is poor for solving problems that have shock (advection problems).

Application of Discontinuity Layout Optimization to Metal Shells and Assemblies

International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT Discontinuity Layout Optimization (DLO) provides a computationally efficient means of determining collapse loads and associated failure mechanisms across a wide spectrum of plasticity problems. The classical DLO method has focused separately on in‐plane and out‐of‐plane plasticity.

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 81-95, March 2026.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

A meshless method in the non-local constitutive damage models

Procedia Structural Integrity, 2016
AbstractThe radial point interpolation method (RPIM), as an advanced discretization approach, is used to analyze concrete structures assuming a non-linear continuum damage model. The theoretical basis of the material, damage characteristics and the computational procedure are presented.

Local continuum consistent peridynamics with bond‐associated modeling and dynamic fracture

GAMM-Mitteilungen, Volume 49, Issue 1-2, March/June 2026.
Abstract This paper explores the theoretical foundations and practical challenges of peridynamics as a nonlocal continuum mechanics method. We establish connections between classical continuum mechanics principles and peridynamics formulations, with a particular focus on understanding how the pairwise force function in peridynamics relates to stress ...

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.
