Dataset for paper "Dislocation Glides in Granular Media"

This repository includes raw data and simulation codes for the paper "Dislocation Glides in Granular Media," authored by F. Nakai, T. Uneyama, Y. Sasaki, K. Yoshii, and H. Katsuragi.

OverviewWe perform numerical simulations using the Discrete Element Method (DEM) implemented in LAMMPS.

Code Structurebase_lammps.lmp: Main LAMMPS simulation scriptbase_initial.c: C code to generate the initial structurebase_various_parameter.sh: Script that modifies parameters in base_lammps.lmp and base_input.txt and executes the simulations with these varying parametersbase_begin_pc.sh: Execution script (please modify to fit your environment)

论文《颗粒介质中的位错滑移》配套数据集

本仓库收录了由F. Nakai、T. Uneyama、Y. Sasaki、K. Yoshii与H. Katsuragi合著的论文《颗粒介质中的位错滑移》的原始数据与仿真代码。

概述：我们采用在LAMMPS中实现的离散元法（Discrete Element Method, DEM）开展数值仿真实验。

代码结构：
base_lammps.lmp：LAMMPS主仿真脚本
base_initial.c：用于生成初始结构的C语言代码
base_various_parameter.sh：用于修改base_lammps.lmp与base_input.txt中的参数，并基于调整后的参数执行多组不同参数下仿真的脚本
base_begin_pc.sh：仿真执行脚本（请根据自身运行环境进行适配修改）

论文配图：
图1与图2为示意图；
图3、图4及图5包含仿真实验数据。

数据文件：
图3(a,b)的轨迹数据可从以下文件获取：
fig3ab_movie_mu0.dump
fig3ab_movie_mu001.dump
fig3ab_movie_mu01.dump
fig3ab_movie_mu015.dump

图3(c)与图4(a,b)的数值数据存储于文件夹Fig3c_Fig4ab_numerical_logscale_data/（内含不同摩擦系数下的实验数据），该数据集通过C语言代码base_logscale.c生成。

图5的数值数据存储于Fig5_numerical_data.txt，通过C语言代码base_calc.c生成。
