Researchers at The University of Tokyo have shown that for amorphous materials, cyclic material fatigue can begin to fracture at the same level of stress as fractures due to constant loading. By ...

This novel approach facilitates the differentiation between near-surface, sub-surface, and internal defect-induced fracture modes, thereby enhancing the reliability of fatigue analysis in advanced ...

The work is published in Communications Materials as “Fatigue fracture mechanism of amorphous materials from a density-based coarse-grained model” (DOI: 10.1038/s43246-022-00293-9).

Metal fatigue happens when metals are exposed to repeated stressors like motions or consistent loads, which can cause microscopic cracks that get worse over time.

Traditional metal alloys can fracture or shatter under sudden external forces that exceed their yield strength, but they are also susceptible to fatigue when subjected to sustained pressure below ...

The National Transportation Safety Board has determined that a fatigue fracture in a critical nose landing gear component led to the emergency landing of Delta flight 1092 in Charlotte, North ...
