SMATool: Strength of materials analysis toolkit

The study of the strength of materials is a cornerstone in material science and engineering, playing a critical role in shaping the progress and application of materials in diverse industrial sectors. The strength of a material is meticulously examined to understand the behavior of the material under different stress conditions and environments, thereby guiding material selection and structural design. Herein, we introduce the SMATool, a computational toolkit for the efficient calculation and analysis of material strength at both zero and finite temperatures for 3D, 2D, 1D, and tubular 2D-based nanostructures and nanotubes, as well as 1D nanoribbons. The toolkit is capable of calculating tensile, shear, ultimate, yield, and indentation (Vickers' hardness) strengths in various dimensions, as well as the energy storage capacity. We conducted several calculations both at zero and finite temperatures to validate the accuracy and reliability of the developed software. The results show that the SMATool package provides accurate predictions that align with existing data on material strength. SMATool integrates seamlessly with widely used electronic structure codes like VASP and Quantum Espresso, providing a user-friendly interface catering to academic researchers and industry professionals. SMATool is useful for either the exploration of the strength of materials or high-throughput new material design. SMATool is open-source and available on GitHub at SMATool@github and at Zenodo at 10.5281/zenodo.10780514.

材料强度研究是材料科学与工程领域的基石，对推动各类工业场景中材料的发展与应用发挥着关键作用。通过对材料强度开展缜密研究，可解析材料在不同应力条件与环境下的力学行为，进而为材料遴选与结构设计提供核心指导。本文介绍了SMATool：一款可针对三维（3D）、二维（2D）、一维（1D）、管状二维基纳米结构与纳米管，以及一维纳米带等多种结构，在零温与有限温度下高效计算并分析材料强度的计算工具包。该工具包可计算不同维度下的拉伸强度、剪切强度、极限强度、屈服强度与压痕（维氏硬度，Vickers' hardness）强度，同时还可评估储能容量。我们通过零温与有限温度下的多组计算，验证了所开发软件的准确性与可靠性。结果表明，SMATool的预测结果与已公开的材料强度实验数据高度吻合。SMATool可与VASP、Quantum Espresso等主流电子结构计算代码无缝集成，并提供友好的用户界面，适配学术研究者与工业从业者的使用需求。无论是用于材料强度特性探索，还是高通量新型材料设计，SMATool均能发挥重要实用价值。该工具包为开源软件，可在GitHub（地址：SMATool@github）与Zenodo（DOI：10.5281/zenodo.10780514）获取。
