2.7 Shrinkage
- Theoretical value: (a=35, : Maximum Shrinkage Strain Ratio)
- The process of finding 'a'
1. Arranging excel data
2. Finding 'a' with using a grapher program
(Converting Excel data into graph shape)
(Standardization of graph through regression analysis)-회귀분석을 통한 그래프 평균화
(Finding 'a' with using shrinkage equation)
3. Finding 'a'=66.39
■ Result discussion
Because we used a broken gage, we're choosing remains of 2 gages.
The greatest error in shrinkage test was that we couldn't get a expected strain; because we had a mistake not exactly attaching gages.
2.8 Creep
