| Abstract: |
| Fracture resistance of concrete affects the safety of buildings during use. In order to find out the blasting of the concrete characteristics of blasting tests on the three groups of different strength concrete and analysis of their effect. Then using ANSYS/LS-DYNA finite element numerical simulation on concrete blasting. Test piece distribution and numerical simulation of explosion stress wave propagation analysis available: concrete strength, the higher the higher ability to resist damage. Cement ratio increase, improves the stickiness in concrete, making stress propagation attenuation rate, eventually leading to damage of concrete strengthening. |
