應用數位影像相關法於土木結構及碳纖維性質與電池表面變化之量測

Abstract

This thesis uses Digital Image Correlation (DIC) technique developed by our laboratory for experimental measurement of deformation of solids and structures for multi-scale and interdisciplinary problems. Digital Image Correlation is a non-contact and full-field measurement technique. The advantage of Digital Image Correlation is the simplicity and convenience of experiment setup. Recording the images of the deformed object, Digital Image Correlation has ability to measure displacement and strain fields rely on our self-developed image processing technique. Using high-speed camera while facing dynamic problem, though the issue of micrometer-scale-deformation problem can also be measured by useing high-resolution microscope. The measurement of deformation for large structures in civil engineering is an important applications and are presented in the paper. The deformation of lithium battery during the charge anf discharge process and the tensile test of carbon fiber composite material are also investigated. The results obtained from the Digital Image Correlation method are compared with that obtained by other experimental techniques to verify its accuracy and reliability.
