| Abstract: | The two methods to monitor crack propagation are developed and a thorough analysis is made for the result of the two methods in break experiment of gypsum plate. It is expounded that the starting velocity of crack propagation is a variable and related to the dynamic process and restrained condition. Also, the error discussion and correction methods are both included. |
