Study on Formative Mechanism of Blasting Crater in Reinforced Concrete under Internal Blast Loading

Abstract:

The variation process of radius and pressure of explosion products in borehole are analyzed in this paper, based on theory of damage and structural mechanics, the formative mechanism of blasting crater in reinforced concrete under internal blast loading is analyzed, the computation method of crater size has been proposed. The calculated results are identical with experimental results on the whole.
