| Abstract: | This paper conducts an experimental study on dynamic fracture speed of three point bending specimen and cylindrical specimen made of epoxy resin by means of silver conductive painting grid. According to the experimental results, the relations between the fracture load, fracture speed and loading speed are discussed and the features of the final fracture surfaces is analyzed in detail by the author. |
