Research on Irreversible Growth Mechanism of PBX due to Thermal Cycling

Current experiments show that the TATB-based polymer bonded explosives (PBX) will experience irreversible growth when suffered temperature cycling load. Although some studies have already been done on this, cause of is still confusing, and mechanism not clear. In order to study PBX under load, an thermal-viscoelastic model established, Based Burgers which considering influence different temperatures creep properties PBX. The analysis shows produced by high low during thermal cycling. Comparing with temperature, rate faster deformation larger at lead
