Moreover, the QC method based on the embedded-atom method (EAM) potential was adopted to observe the fatiguecrackgrowth and expansion characteristics of single-crystal metals under cyclic loading processes. The results showed that after compressive or shear

Considerable attention has been focused on the investigation of the fatiguecrackgrowth behavior in single crystals under cyclic loading using molecular dynamics (MD), which is an effective tool for analyzing the mechanical deformation and mechanical properties of materials at the
microscopic scale [1][2][3][4][5][6][7][8][9][10][11][12][13]. For face-centered cubic (FCC) metallic systems, Wu et al. [10] have investigated the fatiguecrackgrowth in single-crystal Ni under different cyclic loading regimes. They found that different crack propagation and stress distributions lead to
