文摘：This paper shows how to comprehensively characterize the mechanical properties of diverse materials and structures using terahertz imaging. The investigation aims to explore and develop the potential of terahertz imaging by using digital image correlation (DIC) in the detailed characterization of mechanical behaviour. Terahertz waves, situated in the frequency range between microwaves and infrared (0.1 to 10 THz), possess distinctive properties that provide a significant advantage for penetrating various materials and structures without causing damage or ionization. Unique models were created, by using them as direct samples for the experiments. The development also included the creation of a loading post capable of applying forces in three directions compression, traction, and flexion providing a comprehensive approach to the material testing. The techniques of image analysis and processing, specifically in the context of 2D samples are used to obtain the material structures for further analysis. This was done through a series of tests conducted on different materials, such as glass fiber composites, non-composite CHC glass fiber, and a white structure featuring multiple holes. Terahertz imaging played a pivotal role in capturing and analysing the mechanical characteristics of these materials, thereby contributing valuable insights to the broader understanding of their behaviour.
