“…Estimations of the fatigue crack propagation life, based on the Paris law, provide a convenient approach in assessing the fatigue life of the cyclically loaded, large-scale structural and mechanical components [4][5][6][7][8][9][10]. Olowokere and Nwosu [11] demonstrated that the crack propagation life estimated using the Paris law with numerically computed stress-intensity factors (SIFs) using spring elements agreed well with the experimental results obtained from cracked tubular T-joints subjected to axial loads and brace in-plane bending.…”

“…Green and Munz [3] justify their reduction parameter based on the observation that normal linear fracture mechanics methods under predict the through-thickness growth and accounting for the crack closure improves the prediction. Gardin et al [5] studied numerically an experimental thermal fatigue set-up where a surface crack propagates due to cyclic thermal loading. The SIFs calculated numerically using Abaqus finite element software without crack face contact predict crack growth behaviour consistent with the experimental findings.…”

This study considers surface crack behaviour under periodic thermal loads using weight functions and finite element calculations. A surface and subsurface crack opening mode during the load cycle was observed. The subsurface mode where the crack mouth is closed while the crack tip remains open can be more critical for deeper cracks. Crack face contact is required to obtain the subsurface mode both with finite elements and weight functions. A combination of surface and subsurface weight functions can capture the crack behaviour throughout the load cycle. This behaviour is demonstrated using numerous simulations with periodic thermal loads with different extent and frequency.

The drastic severe temperature cycle in an aero‐engine combustion chamber leads to large thermal fatigue stress, which may induce thermal fatigue failure of the combustion chamber. In this paper, thermal fatigue crack initiation and propagation behaviors of GH3230 nickel‐based superalloy sheet specimens with V‐notch were studied under different peak temperatures 800°C, 900°C, and 1,000°C using self‐built thermal fatigue equipment. The temperature, stress, and crack propagation driving force of the V‐notch specimen were discussed in detail. Results show that the thermal fatigue crack initiation life gradually decreases with the increase of the peak temperature. Oxidation caused by high temperature will weaken alloy's strength and accelerate its crack propagation. Higher peak temperature will make the crack propagate faster and the thermal deformation at V‐notch end easier to accumulate. At last, there is a good consistency between fitting curves from the modified Paris formula and the experiment results.
