Monitoring of self-healing cementitious materials through contactless ultrasound [PDF]

MATEC Web of Conferences, 2023
Self-healing cementitious composites provide an alternative to labour-intensive and costly manual repairs. While a cementitious blend possesses an inherent ability to repair its own damage through autogenous healing, an enhancement of the self-healing ...

A method for rapid estimation of residual stresses in metal samples produced by additive manufacturing

Fracture and Structural Integrity
The mechanical methods for measuring residual stresses typically rely on so-called destructive techniques where some stress components can be determined based on part deflection after material removal (cutting, etching, drilling, etc.).
