Abstract: A visual experimental teaching method for the material failure based on the digital image correlation technique is presented in this paper. Taking the concrete material as an example, this presented method is applied in the splitting tension and uniaxial compression tests. The splitting tensile and compressive failure processes are monitored, and the failure modes are analyzed to reveal the failure mechanisms of the concrete material in the splitting tension and compression. The strain distribution of the specimen is obtained using the digital image correlation method. The above results confirm the failure mechanisms of the concrete material and the applicable failure strength theory.

Key words: concrete material, failure process, failure mode, failure mechanism, strength theory
