... using C(T) specimen. For K TH evaluation the tests were based on NACE TM0177 standard [ 2 ], using sharply notched DCB specimens. For this test a 3.5 wt% NaCl aqueous solution with −1.2 V cathodic protection for the in-situ hydrogen charging were used. From the results it was observed that both steels...

... The aim of this paper is to establish a relationship between strain and acceleration, obtained at the center of the specimen, during resonant fatigue test of a full-scale X-65 seamless rigid pipe. The pipe was submitted to five different strain levels. Strain and acceleration on the outer...
