The effect of thickness on mixed mode fracture

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The influence of thickness on mixed mode fracture was investigated experimentally and semiempirically by using compact-tension-shear specimens of LC4-CS aluminum alloy with thickness of 2, 4, 8 and 14mm. The experimental data and phenomenon were analyzed and compared with the theory. The influences of thickness on the direction of crack initiation and fracture toughness were discussed in detail. It is found that in the center of the specimen the direction of crack initiation is strongly dependent on maximum tensile stress except 8mm-thickness considered in this study. The effective stress-intensity factor varies not only with thickness but also with loading mixty, but the law needs further study.
