Fully Relaxing Module – Required Test
The Core Module gives the basic fatigue crack growth rate curve as well as the strain-life curve and crack precursor size.
This module is a pre-requisite for any fatigue analysis.
Experiment Overview:
- static tearing
- fatigue crack growth (20 hour procedure)
- cyclic simple tension to rupture, 2 strain levels
- number of slabs needed for test: 5
Analysis and Reporting / Deliverables
- critical tearing energy Tc
- tensile strain, stress, energy at break
- Thomas Law fatigue crack growth rate curve and its parameters rc and F
- crack precursor size c0 calculation and sensitivity analysis
- computed strain-life, stress-life, and energy-life fatigue curves
