The isochromatic fringes graphs of smooth blasting and cutting seam blasting of pipe protecting borehole wall were obtained upon dynamicphoto-elasticity experiments on both kinds of blasting.
In the paper, the design parameter of the dynamicphoto-elasticity test model was described. In the test, the stress diffusion was explored and recorded really-time. According to the data from …
Dynamicphotoelasticity experiment is conducted, and the isochromatic fringes graphs in the process of smooth blasting of pipe protecting borehole wall is obtained.
