dc.description The steady-state crack growth of 25.4, 50.8, and 127 micrometer thick 1235 aluminum sheets was characterized under quasistatic loading conditions in laboratory air. The crack the length as a function of applied load was measured, and the steady-state crack growth resistance determined using and ANOVA analysis. en_US
dc.description.abstract The steady-state crack growth of 25.4, 50.8, and 127 micrometer thick 1235 aluminum sheets was characterized under quasistatic loading conditions in laboratory air. Because steady-state crack propagation cannot be characterized by conventional linear-elastic (\textit{K}) or elastic-plastic (\textit{J}) crack tip parameters we used a fully-yielded plastic crack growth resistance analysis to identify when cracks reached steady-state propagation conditions. At steady-state a constant, characteristic crack growth resistance of 60 MPa, 95 MPa, and 93 MPa was observed for the 25.4, 50.8 and 127 micrometer thickness sheets, respectively. This steady-state crack growth is dramatically different from conventional linear elastic and elastic plastic crack growth because the plastic zone is uncontained and extends across the remaining ligament. en_US
