Molecular dynamics simulations are employed to demonstrate that adhesive contact formation through classical jump-to-contact is mediated by extensive dislocation activity in metallic nanoparticles. The dislocations generated during jump-to-contact are completely annihilated by the completion of the adhesive contact, leaving the nanoparticles dislocation-free. This rapid and efficient jump-to-contact process is pseudoelastic, rather than purely elastic or plastic.
