A multi-phase SPH simulation requires days to run, but a single-phase simulation can give comparable results in hours. Tailoring the Static and Dynamic Mechanical Properties of Although the research of the self-assembly of tri-block copolymers has been carried out widely, little attention has been paid to study the mechanical properties and to establish its structure-property relation, which is of utmost significance for its practical applications. Here, we adopt molecular dynamics simulation to study the static and dynamic mechanical properties of the ABA tri-block
