Reliability Module
If ordered with FPM-C, includes analysis of strain life curve dependence on probability of occurrence.
The Reliability Module characterizes the rate of occurrence of crack precursors of a given size. This information is useful for estimating likely strength or fatigue failure rates for quality/warranty applications.
Recommended when probability of failure needs to be estimated.
Experiment Overview:
- 50 simple tension pull-to-failure experiments
- static tearing, 3 replicates
- number of slabs needed for test: 10
Analysis and Reporting / Deliverables
- summary statistics for pull to failure (strain, stress, energy at break)
- calculation of crack precursor size distribution c0
- Weibull distribution parameters relating frequency of occurrence to size of crack precursor
Use with:
- Reliability estimates
- Weibull distribution
