Investigation of materials structure and failure mechanism by using imaging techniques is always useful and fruitful to understand and control the properties of the materials. Now it become possible to model and simulates the materials structure and failure mechanism to some extent by using the information from the analysis of those imaging data. My project is 3D modeling and simulation of failure mechanisms of pipeline steel by Environmental Assisted Cracking (EAC). Thanks to high resolution (by using synchrotron radiation) computed tomography to help for producing 3D image of structure of materials with microscopic resolution which overcome several limitations in 2D imaging techniques. An independent tensile and rotational sample stage was designed and fabricated for conducting the in-situ 3D imaging experiments at Canadian Light Source (CLS) to visualize and demonstrate the crack initiation, propagation in 3D inside the materials using synchrotron radiation tomography. The established in-situ 3D synchrotron radiation tomography experimental technique and complementary in-situ 2D SEM/EBSD experiments would be a great tool to get true 3D features along grain features will help us to get a robust model of failure of pipeline steel by EAC.
