Particle morphology influences the mechanical behavior of granular soils. Generating particles with realistic shapes for discrete element method simulations is gaining popularity. However, it is still challenging to efficiently generate very angular particles with less computational cost. Addressing this challenge, this paper introduces a novel noise‐based framework for generating realistic soil particle geometry. Noise algorithms are utilized to apply random variations with certain morphological patterns on the surface of the base geometry (e.g., a sphere), thereby generating a variety of particles with morphological patterns ranging from very angular to rounded. In addition, the base geometry can be replaced with other geometries including real particle scans, allowing rapid generation of realistic particles with morphological characteristics of the base geometry. The framework stands out for its simplicity, the wide range of particle morphologies generated, reducing the need for extensive computation and scanning, and provides a new idea for the granular soil behavior simulations.

一个基于噪声的框架,用于随机生成具有真实几何形状的土壤颗粒
颗粒形态会影响颗粒土壤的力学行为。为离散元方法仿真生成具有真实形状的粒子越来越受欢迎。然而,以较低的计算成本高效生成非常有棱角的粒子仍然具有挑战性。为了应对这一挑战,本文引入了一种新颖的基于噪声的框架,用于生成逼真的土壤颗粒几何形状。噪声算法用于在基础几何体(例如球体)的表面上应用具有某些形态图案的随机变化,从而生成具有从非常棱角到圆形的形态图案的各种粒子。此外,基础几何体可以替换为其他几何体,包括真实粒子扫描,从而可以快速生成具有基础几何体形态特征的真实粒子。该框架以其简单性、生成的各种颗粒形态而著称,减少了对大量计算和扫描的需求,并为颗粒土壤行为模拟提供了新思路。
