Abstract

This paper describes a calibration procedure that is intended to eliminate as much as possible several error sources very common in calibration procedures, which are not frequently discussed and analyzed. Error sources in calibration procedures are as much important as the needed precision increases. In the present situation because is intended to study the fatigue crack initiation, until 1 mm, every detail may become very important. It's also an aim of this work to identify particular features of the system used in this work ( Pulsed DCPD - Pulsed Direct Current Potential Drop) applied to fatigue round specimens. 1 Introduction Nowadays one may divide fatigue crack length measurement techniques with potential systems in three variants according to the electri
