| Abstract: | Simulation software Hyperworks was used to carry out the finite element simulation of Q345R steel charpy impact test. Explicit dynamic analysis method was used to calculate the impact energy, and the results were compare with experimental data. Analysis shows that the simulation results are satisfactory. For the analysis of the effect of specimen size on simulation results, five kinds of small size specimen were used to carry out impact process simulation. Analysis shows that,when the specimen thickness is not less than 5 mm, energy density is closer to standard sample result. |
