Numerical Simulation and Experimental Studies on Impulse of Flexible Explosive
摘要
Abstract
One-dimensional numerical calculation is carried out to simulate the impulse produced by contact explosion of different thickness of flexible explosive (FEX) on several base materials. Experimental measurements were conducted to test the impulse of the FEX with thickness of 0. 4 mm using self-made impulse probe. The measured impulse is 1234 Pa · s and agreed well with calculated results. The simulated results show that the impulse quantity of FEX increases proportionally to its thickness (the impulse quantities are sensitive to the shock wave impedance of contacted base materials, and the bigger of the shock wave impedance, the more imparted impulse.关键词
