Interaction of Multiple Cracks on Crack Propagation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000 There is interaction among multiple cracks which are initiated in a plane surface by fatigue or environmentally assisted cracking. And it is observed that these cracks may coalesce as they approach each other. In this study, the interaction of multiple cracks with different relative locations and lengths was evaluated using a finite element method ...

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Fatigue and fracture: Overview [PDF]
, 1984 A brief overview of the status of the fatigue and fracture programs is given. The programs involve the development of appropriate analytic material behavior models for cyclic stress-strain-temperature-time/cyclic crack initiation, and cyclic crack ...
