Outline of Final Research Achievements |
Fracture of materials induces catastrophic accident so that it is essential to prevent the fracture in order to increase the reliability of the materials in use. In this study, the stress field which is due to the internal stress of dislocations was obtained around a crack tip, measuring the shift of lattice points from their equilibrium positions. The existence of shielding field which is theoretically expected around the crack tip was experimentally cleared in an atomistic scale.
