Three-dimensional crack closure behavior

A crack closure measurement technique involving fatigue striations was used to produce a 3-dimensional crack opening load profile for 2024-T351 aluminum alloy. The crack opening load profile, determined through the specimen thickness, was compared with crack opening load measurements made with strai...

More Information
Summary:A crack closure measurement technique involving fatigue striations was used to produce a 3-dimensional crack opening load profile for 2024-T351 aluminum alloy. The crack opening load profile, determined through the specimen thickness, was compared with crack opening load measurements made with strain gages and displacement gages. The results of this study indicate that a significant 3-dimensional variation in crack closure behavior occurs in the alloy examined. An understanding of this phenomenon is important in understanding crack growth behavior, predicting crack shape changes, and interpreting “standard” crack closure measurement techniques.
