Abstract
The internal ligament will undergo severe deformation and fracture when the nanoporous metal is loaded. Molecular dynamics simulates the uniaxial tensile fracture of a single ligament model of nanoporous copper at the atomic level. The side effect of the fracture energy of nanoporous metal ligaments and the relationship between the porosity of nanoporous metal and the fracture energy are explored. On this basis, the fracture toughness of nanoporous metal was obtained. The results show that phase transition is ligament tensile fracture’s main energy consumption mode. And the average proportion of phase transition energy in fracture energy is 61%. The fracture energy of nanoporous metal ligaments has an obvious size effect. Last, the fracture toughness of nanoporous metal with different porosity is given.
