摘要/Abstract

摘要： 建立较准确的微观胞体结构模型是一项极其复杂但极具价值的一项工作。利用Python,对Abaqus进行二次开发,实现规则Kelvin单胞结构、规则Kelvin多胞结构和随机Kelvin多胞结构等开孔泡沫结构的参数化设计和自动化建模,并对建模思路、关键算法的设计与实现加以说明。以泡沫铝为例,分别对规则Kelvin结构和随机Kelvin结构的开孔泡沫铝在准静态压缩过程中的力学行为进行了对比分析研究。研究成果对随机Kelvin胞体结构的开孔泡沫材料的数值仿真研究具有一定的参考价值。

Abstract: It is very difficult to model an applicable microstructure for the open cell foams. Using the Python scripting language and the commercial code ABAQUS, the structures for regular Kelvin cell, regular Kelvin open cell foams and random Kelvin open cell foams were designed and modeled automatically. The methodology for modeling, the design and implement for the key algorithms in the process of modeling were presented. For the open cell Aluminum foam, the regular Kelvin cell open cell model and the random Kelvin cell open cell foams model were developed, respectively, and the mechanical responses of them under quasi-static compressive load were numerically investigated and compared.

Key words: algorithms design, open-cell foam, Python, Abaqus, random Kelvin cell, aluminum foam
