| Abstract | The present thesis investigates the strain distribution in structures by leveraging the principles of the sampling moiré method. This non-contact measurement technique offers great potential for accurately assessing structural deformations without requiring physical access to the target points. By employing the sampling moiré method, the research aims to obtain detailed strain distribution data, which, in turn, enables the prediction of potential damage to structures. The methodology employed in this study involves the careful implementation of the sampling moiré technique to capture deformation patterns in the target structures. The non-contact nature of the method ensures minimal interference with the structure, making it a valuable tool for measuring a wide range of materials. Upon capturing the images, rigorous image processing techniques are applied to analyze the data and extract the strain distribution. The resulting strain data provides essential insights into the behavior of the structures under various loading conditions, helping to identify areas susceptible to damage and potential failure. The significance of this study lies in its contribution to the field of structural health monitoring and assessment. The non-invasive nature of the sampling moiré method not only streamlines the measurement process but also enhances safety by eliminating the need for physical access to critical structural components. By predicting potential damage based on strain distribution, this research can aid in the timely implementation of preventive measures, prolonging the service life of structures and ensuring public safety. In conclusion, the thesis demonstrates the effectiveness of the sampling moiré method in accurately characterizing strain distribution in structures. The findings offer valuable insights into the structural health of various components, guiding engineers, and practitioners in making informed decisions to ensure the reliability and safety of civil infrastructure. Furthermore, the non-contact nature of the method opens new avenues for efficient structural assessment, presenting a promising avenue for future research in the field of structural engineering. |
