The ghost fluid method (GFM) provides a simple way to simulate the interaction of
immiscible materials. Especially, the modified GFM (MGFM) and its variants, based on the …

A friction model for hyper-elastic solid materials was proposed for the simulation of complex
shear impacts in a Eulerian framework. The interfacial status of multi-material interactions …

In this work, an elastic-perfectly plastic model in two-dimensional planar geometry is studied
and a new HLLC-type approximate Riemann solver (HLLCN) is put forward. The main …

An explicit moving boundary method for the numerical solution of time-dependent hyperbolic
conservation laws on grids produced by the intersection of complex geometries with a …

Abstract Background and Objective: Numerical simulations are valuable tools for studying
cardiac arrhythmias. Not only do they complement experimental studies, but there is also an …

The equation of state (EOS) plays a crucial role in hyperbolic conservation laws for the
compressible fluid. Whereas, the solid constitutive model with elastic-plastic phase transition …

Abstract Based on the Modified Ghost Fluid Method (MGFM) and Modified Ghost Solid
Method (MGSM), the Modified Ghost Method (MGM) is developed to deal with the combined …

The analysis of deformations of structures immersed in water due to explosion waves is
important for off-shore oil and marine applications. A challenging issue in these problems is …

We propose a robust approximate solver for the hydro-elastoplastic solid material, a general
constitutive law extensively applied in explosion and high speed impact dynamics, and …

The exact Riemann solver for one-dimensional elastic-perfectly plastic solid has been
presented in the previous work [S. Gao and TG Liu, Adv. Appl. Math. Mech., 9 (3), 2017, 621 …
