Digital Image Correlation

Digital Image Correlation (DIC) is a technique used to measure how objects deform and move under stress by analyzing images. It involves taking high-resolution pictures of an object's surface before and after it experiences force. Specialized software compares the images, tracking tiny changes in patterns or textures to calculate how much the surface has shifted or stretched. This non-contact method provides detailed, full-field measurements of displacement and strain, helping engineers and scientists understand material behavior, assess structural integrity, and improve designs without physically altering or attaching sensors to the object.
