| Abstract Scope |
The development of higher-performance materials necessitates a more comprehensive understanding of their failure mechanisms, especially as materials are pushed to their mechanical and structural limits. The simultaneous drive toward miniaturization and increased strength challenges the applicability of classical fracture mechanics, which often fall short at smaller length scales. In this work, we demonstrate that a combination of miniaturized in situ scanning electron microscopy experiments and in situ nanodiffraction techniques, integrated with machine-assisted data analysis, allows for precise resolution of stress–strain fields within micro-scale fracture specimens. This advanced approach not only enables the execution of elastic–plastic fracture experiments at the micrometer scale, but also provides a framework for evaluating limits of traditional fracture models as component sizes continue to shrink. Our methodology opens new possibilities for assessing mechanical integrity in next-generation micro- and nanoscale devices, offering critical insights for the design of more resilient and reliable materials. |
