Abstract

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.

基于体素的计算机断层扫描有限元分析方法和数字图像相关系统验证

在航空航天工程、复合材料开发、地质学和生物力学等各个领域，了解异质材料的力学行为正变得越来越重要。虽然已有大量相关文献，但传统方法通常依赖于商业软件包。本研究提出了一个基于计算机断层扫描（CT）的有限元（FE）分析框架，在大部分工作流程中使用开源软件。我们的工作主要集中在三个关键方面：1.结合空间变化的机械属性和定义明确的边界条件生成网格。2. 通过与数字图像相关（DIC）系统的测量结果进行比较，验证 FE 结果。 3. 在整个过程中使用开源软件，使其更易于使用且更具成本效益。
