We are happy that the reviewers of our manuscripts saw the originality of our project on the impact response of nanoscopic aluminum/polyurea nanostructures. For example, one reviewer mentioned, “This manuscript is very interesting and appears to be novel and unique.”, and another comment was “The paper is novel and uses state-of-the-art simulation techniques.” We published 3 papers based on this project.
The molecular dynamics (MD) simulations in our first paper (
https://doi.org/10.1016/j.commatsci.2020.109951) were conducted at an impact speed of 0.5 km/s. Its main focus is on the interfacial mechanisms associated with non-penetrating impacts including dislocation processes in aluminum.
Our second paper (
https://doi.org/10.1115/1.4048319) presents the computation of the minimum velocity required to penetrate a target (i.e. the ballistic limit velocity) using MD simulations and continuum-based models.
The MD simulations in the third paper (
https://doi.org/10.1016/j.commatsci.2021.110504) were conducted at an impact velocity of 1.5 km/s. Its main focus is on the energy dissipation mechanisms associated with complete penetration.
