The research on velocities of fragments from internal explosion in reinforced concrete

摘要

The movement of concrete fragment from internal explosion in reinforced concrete is analyzed, and a model is built for the description of fragments' acceleration. Make use of stress wave theory and EOS of detonation product, the velocity of fragment could be determined, with the interaction between steel and concrete and their deformation harmony considered. The computational results are compared with experimental ones with an analysis for the error.
