 We conducted molecular dynamics simulations of plate impact tests of polyethylene to obtain molecular-level insights on two common approximations associated with the interpretation of shock pressure and spall strength. Our results revealed

(1) The free surface approximation can slightly underpredict the shock pressure in the polymer.

1. Introduction

Our latest article “Quantum and classical molecular dynamics simulations of shocked polyurea and polyurethane” is available freely for 50 days from this URL: https://authors.elsevier.com/a/1eJem3In-urdzV

Highlights of the article are as follows:

• Quantum molecular dynamics were used to compute shock Hugoniot data up to 75 GPa.

• The shock response of polyurea and polyurethane are remarkably similar.
