Life prediction of spot-welds: a fatigue crack growth approach
… Stress intensity factors are used with the Walker equation to develop two crack growth approaches to the problem. The predictions fit data for lap joint configurations well, but not so for peel joint geometries.

Tensile, Creep, and Fatigue Behaviors of Thermoplastics Including Thickness, Mold Flow Direction, Mean Stress, Temperature, and Loading Rate Effects
… review. In terms of effectiveness, the Walker equation and a simple model with a mean stress sensitivity factor (¿¿) proved to be the most effective. Incremental step cyclic deformation tests were performed to generate cyclic stress-strain curves to enable the determination of …

Fatigue Crack Growth Analysis with Finite Element Methods and a Monte Carlo Simulation
… growth in 7075-T6 aluminum alloy. The Paris, Walker, and Forman fatigue crack growth models were fit the experimental data. The Walker equation best fit the data since it incorporated R-ratio effects and had a similar Root Mean Square Error (RMSE) compared to the other models. There was …
