What is the latest method for examining the shape and deformation of structures, known as the Sampling Moiré Method?
Many objects undergo significant deformation when force is applied, ultimately leading to failure. By studying this deformation, it becomes possible to achieve prevention, prediction, and repair.
Many structures built during the period of rapid economic growth are approaching the end of their lifespan. In particular, to ensure the safety of infrastructure such as bridges and buildings, it is necessary to evaluate their integrity. One important method for confirming their integrity is to examine the shape and deformation of the structures. Additionally, it is essential to verify the strength of newly developed structures with real-life tests. Representative methods for examining the shape and deformation of structures include the "Image Correlation Method," "Grid Method," "Moire Method," and particularly the newer "Sampling Moire Method." [Features] - Image Correlation Method: Randomly capture images and find patterns with the same features after deformation to investigate displacement. - Grid Method: Capture images of an evenly spaced grid pattern and examine the phase of the grid to determine displacement. - Moire Method: Overlay grids before and after deformation to investigate displacement through the resulting Moire fringes. - Sampling Moire Method: Investigate displacement by capturing only the grid after deformation. *For more details, please refer to the PDF document or feel free to contact us.
