Develop materials to resist fatigue

Event Description

Most materials suffer from a disease: fatigue. Symptoms include degradation of properties and growth of cracks under cyclic stretch. These materials are unfit for applications involving prolonged and cyclic loads. A crack grows in a material because the crack tip concentrates stress. Recently, we have been developing materials that resist fatigue by de-concentrating stress, through mechanisms at either microstructural or molecular scale. This talk describes the mechanics and implementations in materials.
