Deformation and fracture simulation of Ni3Al alloy under shock loads

Abstract

A theoretical study of the deformation and fracture behavior of Ni3Al alloy under shock loading has been carried out. The finite element method simulation was used within the approach that combined modeling in terms of the dislocation kinetics of alloys with the L12 superstructure and the mechanics of a deformable solid. The dislocation kinetic model of the alloys with the Ll2 superstructure defined the hardening of Ni3Al punch and plate materials, while the model of the mechanics of a deformable solid described deformation of the macrovolume.
