Crack-Tip Displacement Fields and JR-Curves of Four Aluminum Alloys
1992The JR-curves associated with small crack growth in 0.8-mm-thick 2024-T3, 2024-0, 5052-H32 aluminum and 2091-T3 aluminum-lithium cruciform specimens and 2024-T3 and 2024-0 aluminum single-edge-notched (SEN) specimens are presented. The cruciform specimens were loaded uniaxially and biaxially.

Abstract In this work, the shielding effect on growing fatigue cracks under different overload levels is evaluated by estimating stress intensity factors from the analysis of crack tip displacement fields measured by digital image correlation (DIC). A novel model called CJP is implemented to characterise crack tip displacement fields. The retardation

Most of fracture analyses often require an accurate knowledge of the stress/displacement field over the investigated body. However, this can be sometimes problematic when only one (singular) term of the Williams expansion is considered. Therefore, also other terms should be taken into account.

The fatigue crack-tip deformation in the 7075-T6 aluminum alloy has been studied by moiré interferometry, which is a coherent optics technique for full-field in-plane displacement measurements in the submicrometre range. For constant-amplitude-loading conditions the local strain distributions and the crack-tip plasticity have been correlated with ...
