Correlation of Bending Fatigue Data for Two Different Specimen Designs and at Different Gaseous Hydrogen Exposure Levels for 304 Stainless Steel
Faculty Sponsor
Patrick Ferro, Gonzaga University
Research Project Abstract
Bending fatigue specimens of 304 stainless are subjected to gaseous hydrogen exposure to study possible embrittlement effects from the hydrogen exposure. The specimens are subjected to hydrogen at pressures up to 138 MPa at 300°C for up to three weeks. Two different specimen geometries have been used in the experimentation. The current work seeks to correlate the data for each of the two different specimen geometries. Additional work includes measuring the maximum stress on specimens during bending fatigue. To measure the stress, strain gages are attached to specimens. The measured stresses are compared with modeling results.
