- Conclusions:Focused ultrasound has therapeutic effect on dermis but no accumulated damage to the skin treated at regular intervals.
- In the analysis, the total strain amplitude as well as the rules of accumulative damage are used for the research of the fatigue life.
- STUDY ON THE DYNAMIC ACCUMULATION DAMAGE FOR THE STAINLESS STEEL(00Cr18Ni9)
- The results as follow:The damage duration in the area was from September to November of 2004,and the accumulative damage rate was 34.25%,especially during September of 2004,which was up to 17.42%.
- An accumulation of data to be processed.
- An accumulation of work is waiting to be done.
