主要内容
“弹性和机械性能的高效计算和可视化对于材料的选择和新材料的设计至关重要。该工具包标志着材料弹性和机械性能计算分析和可视化方面的重大进步，对材料选择和设计至关重要。该增强版超越了弹性张量、杨氏模量、体积模量和泊松比等标准计算。它引入了计算最小热导率、线性可压缩性、渲染克里斯托弗方程和弹性能量密度的功能。值得注意的是，它集成了先进的可视化工具，包括与 Plotly 和 Elate 网络平台的兼容性，可用于基于网络的交互式属性探索。它的一个主要特点是实现了管状二维纳米结构和纳米管的二阶弹性常数（SOEC）。利用高效应变矩阵集（OHESS），该工具包现在可以在零温和有限温度下高效计算一维、二维和三维的弹性常数和机械性能”——取自文章摘要。
