Study on Detonation Features of Low Powder Detonating Fuse in the Bending Condition

摘要

Detonation of low powder detonating fuse is studied in numerical simulation and experiments in bending conditions using LSJDYNA3D. The results show that pressure of the explosion and detonation velocity are decreased in the same section areas after bending. In bending conditions, detonation wave is similar to small angle corner diffraction. So the detonation velocity is lower than normal velocity.
