Fatigue Analysis of Crack Growth Rate and Path in Aluminium Alloy 2024-T3 Under Mix Mode Loading

  Rohinkumar I. Patel,  Mr. Chetan S. Jadav

These paper methods for estimating fatigue crack growth (FCG) under mode I, mixed mode I/II loading. The experimental part of the study consists of fatigue crack growth on thin plate. For the above specimen types, both Mode I and mixed mode FCG tests are first performed. To find fatigue crack growth path in aluminium alloy 2024-T3 plates under constant amplitude loading (CA). The tests were performed on a standard servo hydraulic fatigue testing machine (MTS810).Find fatigue crack growth path. Further FEA analysis is done by XFEM based algorithm available in the finite element code ABAQUS is explored with respect to its performance in estimating crack growth paths. FEA software version (ABAQUS/CAE 6.13.1) is used and the results suggest that using mode I, mode I/II experimental data, both experimentally and FEA analysis estimation of pure mode & mixed mode fatigue crack growth is possible.
