    Effect of the Local Stress State on the Fracture Mechanism of Metallic Materials with Different Lattices under Single Loads

    The study discusses the effect of the local stress state at the crack tip on the fracture behavior of coarse- and ultrafine-grained bcc, fcc and hcp materials under single impact and static loads. The local st...
