ReaxFF molecular dynamics simulations on thermal decomposition of RDX-based CMDB propellants

Journal of Molecular Modeling, 2022
Abstract ReaxFF molecular dynamics (ReaxFF MD) simulations were performed to study the thermal decomposition property of cyclotrimethylenetrinitramine (RDX) based composite modified double base (CMDB) propellants. The intermediate products and final products of the decomposition of RDX based CMDB propellants at 2000 K, 2500 K and 3000 K are ...
