The research measured cracks by visualizing them through mechano- luminescence(ML) paint. By applying M-L paint on the surface of the specimen and using the 3-point bending test. Through the results of this research, we confirmed the crack propagation speed by section and the mechanical correlation such as between loads and cracks and between deflection and cracks, which means this research was quite successful in analyzing the characteristics of cracks.
