摘要：

Stress intensity factors (SIFs) are important parameters for evaluating structural reliability. This work combines CT in situ uniaxial compression experiment to study the main crack propagation trajectories of the reactive powder concrete (RPC) specimens. The three-dimensional ( 3D) displacement fields of RPC specimens with 3D surface cracks were analyzed using a 3D digital image correlation (3D-DIC) method. The 3D-DIC method was used to calculate the 3D surface crack SIFs of RPC specimens at different inclination angles, and the influence of crack inclination angles on SIFs was analyzed. The study found that the distribution pattern of SIFs calculated by the 3D-DIC method is consistent with the results obtained by the numerical method.
