Less attention has been given to fatigue loading for negative stress ratios (R &amp;lt; 0). In this work the results of crack propagation tests of middle-crack tension M(T) specimens of a normalized medium carbon steel DIN Ck 45 for a wide range of stress ratios from 0.7 \u2a7e R \u2a7e -3 are presented. Crack closure loads were measured with the compliance technique at test frequency, using a data acquisition system. Negative crack closure loads were found for negative stress ratios R \u2a7d -1, which can explain higher crack propagation rates and accelerations in crack growth during variable-amplitude tests where compressive loads of different stress ratios are present.<\/jats:p>","DOI":"10.1520\/stp15765s","type":"book-chapter","created":{"date-parts":[[2009,3,4]],"date-time":"2009-03-04T21:34:46Z","timestamp":1236202486000},"page":"321-336","source":"Crossref","is-referenced-by-count":2,"title":["Measurement of Fatigue Crack Closure for Negative Stress Ratio"],"prefix":"10.1520","author":[{"given":"FFJ","family":"Romeiro","sequence":"first","affiliation":[{"name":"Polytechnic Institute of Leiria 1 Assistant professor , Department of Mechanical Engineering, , Av.
