Abstract
The minimal strain distribution around a fatigue crack-tip initiation is eval- uated by coupling a lithographically deposited grid onto the sample surface and one of two proposed displacement calculation methods. Low-carbon steel flat samples were submitted to fatigue conditions using a new piezoelec- tric test system that permits in-situ Scanning Electron Microscope (SEM) tests. The fine period of the grid (2 /mi) allows a description of the min- imal strain field
