Abstract

Abstract

The influence of low pressure on polymer-bonded explosive (PBX) interfacial damage under temperature fluctuation was investigated. Firstly, a 2D geometric model was built with the Voronoi method. The change of interfacial bonding property was studied under temperature changes, with the particles considered as elasto-plastic, the binder as 2-layer viscoplastic and the zero-thickness cohesion model to reflect the interfacial bonding conditions. Then, the inhibition effect of low pressure on the interfacial damage of PBX under temperature fluctuation was studied based on the thermo-mechanical coupling method, and the curve of normal traction changing with low pressure was fitted. The results show that, the initial damage is mainly caused by the tangential traction of the interface in the heating stage, and the interfacial damage is mainly caused by the normal traction in the cooling stage. What’s more，the temperature drop is more likely to cause interfacial damage than the temperature rise. Regardless of temperature rise or fall, a certain low pressure can inhibit the interfacial damage, but a too high pressure may cause new damages; to inhibit the interfacial damage, the pressure required in the cooling process should be higher than that in the heating process, which is consistent with the larger interfacial damage in the cooling stage.
