Application of DIC System in the Tensile Test of Medium and Heavy Plate

Abstract:

Digital image correlation (DIC) is a kind of non-contact strain measurement method. It could provide deformation information of a specimen by processing two digital images that are captured before and after the deformation. the application of DIC method in performance testing and evaluation of new materials has great superiority over the traditional methods in the aspects that help to explore the features of new materials, such as mechanical performance, deformation mechanism and dynamic and static performance^[1-. Tensile test of 8mm steel plate based on DIC is introduced in this paper, this test is easy operated and high accuracy. It can not only get all the data that traditional method done, but also reflect the full range strain, strain history and strain rate. It can also transform the result among different type strain. The experiments based on DIC method of medium and heavy plate can help to learn the properties of material like this kind much more comprehensively, reduce testing time and promote the wide application of new material in manufacturing.
