Research Abstract

Residual stress is an important parameter for evaluating fracture phenomena such as fatigue, stress-corrosion cracking, or brittle fracture. Relationship between heterogeneity in microscopic region of crystal structures and residual stress distribution affects fracture characteristics. Microscopic residual stress evaluation is therefore effective for materials design and mechanism study of fracture behavior, by using not only numerical analysis approach but also direct measurement. We challenge indentation technique for microscopic residual stress measurement. Both of Vickers-type and Knoop-type indenters are used for obtaining load-displacement relationship during whole loading and unloading processes, then residual stress is theoretically calculated. Directions and components of residual stress are precisely evaluated by using the proposed method.
