Understanding the mechanical behavior of heterogeneous materials is becoming increasingly crucial across various fields, including aerospace engineering, composite materials development, geology, and biomechanics. While substantial literature exists on this topic, conventional methods often rely on commercial software packages. This study presents a framework for computed tomography (CT) scan-based finite element (FE) analysis of such materials using open-source software in most of the workflow. Our work focuses on three key aspects:1.Mesh generation that incorporates spatially varying mechanical properties and well-defined boundary conditions.2.Validation of the FE results through comparison with digital image correlation (DIC) system measurements.3.Open-source software utilization throughout the entire process, making it more accessible and cost-effective.This work aims to demonstrate the effectiveness of this framework for analyzing heterogeneous materials in various fields, offering a more accessible and affordable approach
了解异质材料的力学行为在包括航空航天工程、复合材料开发、地质学和生物力学在内的各个领域正变得越来越重要。虽然关于这个主题有大量文献,但传统方法通常依赖于商业软件包。本研究提出了一个框架,用于在大多数工作流程中使用开源软件对这类材料进行基于计算机断层扫描(CT)的有限元(FE)分析。我们的工作集中在三个关键方面:1. 结合空间变化力学性能和明确边界条件的网格生成。2. 通过与数字图像相关(DIC)系统测量结果进行比较来验证有限元结果。3. 在整个过程中使用开源软件,使其更易于获取且更具成本效益。这项工作旨在证明该框架在分析各个领域异质材料方面的有效性,提供一种更易于获取且价格合理的方法
