study of pull-out and load transfer mechanisms in aluminum matrix nanocomposite by molecular dynamics simulations

This study explores the load transfer and cnt pull-out mechanisms in aluminum-carbon nanotube (al-cnt) composites compared to pure aluminum matrix using molecular dynamics (md) simulation. the results show that al-cnt composites show a 45% improvement in strength compared to pure aluminum, with a load transfer mechanism enhancing stiffness and strength. the pull-out mechanism, however, only marginally increases strength but exhibits a higher failure strain. the study also highlights that excessive cnt fracture or pull-out can reduce mechanical properties. the findings provide valuable insights into the deformation behavior of al-cnt composites and offer opportunities for tailoring their properties for specific applications.
