               Abstract:  With the development of modern weapon systems, the requirements for the survivability of ammunition in various
               complex environments have been continuously increasing. During the processes of storage, flight, and combat, ammunition
               may be subjected to extreme impact loads such as high-speed impacts, shock waves, bullet and fragment impacts. The external
               impacts can induce plastic deformation and fracture of the ammunition casing, and even detonate the internal explosives. These
               responses involve complex phenomena including impact loading, thermo-mechanical coupling of materials, chemical reactions
               of explosives, and blast effects, representing a typical dynamic response problem of reactive materials under extreme thermo-
               mechanical coupling conditions. Accurately predicting the responses of ammunition under impact loading is critical for its
               design optimization and safety assessment. Based on the Hot Optimal Transportation Meshfree (HOTM) method, a meshfree
               numerical approach was proposed to accurately predict the ammunition responses under different impact loadings. Meanwhile,
