X射线断层扫描在材料力学行为研究中的应用

摘要

X射线断层扫描可以无损地对材料内部的微观结构、缺陷及损伤进行三维成像,将其应用于材料的力学行为研究具有明显的优势.在文中作者结合研究经验和国内外大量文献,系统地介绍了 X射线断层扫描的基本原理及其在损伤观测(实验研究)、全场测量和仿真分析等领域的应用,方便了解X射线断层扫描及其在材料力学行为研究中的应用方法.%X-ray Computed Tomography allows the microstructures, defects and damages in the bulk of materials being imaged in three-dimension nondestructively, thus it has advantages to be applied to study the mechanical behaviors of materials. The principle of X-ray Computed Tomography and its applications to damage observations (experimental study), full-field measurements and simulation analysis are presented comprehensively in this paper in the basis of authors' research experiences and literature. It allows the readers to understand X-ray Computed Tomography and the methods of its applications to study the mechanical behaviors of materials rapidly.
