Elucidating the impact of microstructure on mechanical properties of phase-segregated polyurea: Finite element modeling of molecular dynamics derived microstructures

Kavli Affiliate: Brett P. Fors | First 5 Authors: Steven J. Yang, Stephanie I. Rosenbloom, Brett P. Fors, Meredith N. Silberstein, | Summary: Phase-segregated polyureas (PU) have received considerable interest due to their use as tough, impact-resistant coatings. Polyureas are favored for these applications due to their mechanical strain rate sensitivity and energy dissipation. Predicting […]
