Mechanical Property's Measurement of X-Bomb's Explosive Column

摘要

This paper put forward a new method which base on inactive method. But it is the combination of the static and dynamic. Basing on this method the material testing machine has been improved. Using the machine, mechanical property of X-bomb's explosive column has been tested. The Young's modulus is 4.73GPa, yield limit is 8.67MPa, Poisson's ratio is 0.35, shearing strength is 3.15MPa and compressive strength is 9.60MPa. Expand exploded hole of the column has been studied on the mechanical property. Testing result is model sample was damaged when the load is 0.33 MPa.
