“…The residual stress redistribution would occur when the local stress exceeds the yield stress σ s 41 . The residual stress relaxation usually depends on the number, the amplitude, and the stress ratio of cyclic loading 41 . The greater the maximum stress is, the more obvious the stress relaxation.…”

“…The FE model under cyclic tensile loading was generated to investigate the residual stress relaxation process. It can be inferred that the residual stress relaxation usually depends on the number, the amplitude, and the stress ratio of cyclic loading, 41 so for each type of post‐impacted specimen, all levels of cyclic loading shown in Figure 6 were applied to the specimens to simulate the relaxation process of the residual stress. The method for developing the cyclic tensile model is illustrated by a flowchart shown in Figure 12A.…”

“…41 The residual stress relaxation usually depends on the number, the amplitude, and the stress ratio of cyclic loading. 41 The greater the maximum stress is, the more obvious the stress relaxation. It is important to consider the residual stress relaxation for predicting the fatigue lifetime of post-impacted sheets because the stress concentration and tensile residual stress around the impact dent make it easier for the local stress to exceed the yield stress.…”

This paper presents a fatigue life prediction model of post‐impacted sheets considering the effects of dent size and stress ratio. Low‐velocity impact tests at four different impact energies were performed on specimens cut from sheets of 2524‐T3 and 7075‐T62 aluminium alloy. Following the impact tests, static tensile and uni‐axial constant amplitude and block spectrum fatigue experiments were conducted. Numerical models were generated to determine the initial residual stress patterns, residual stress relaxation, and stress concentration factors around the impact dent. The S‐N curves and corresponding stress concentration factors and relaxed residual stresses of three of the post‐impacted specimens were used to determine the model parameters. Good agreement was achieved between the predictions and experimental results, and it has been demonstrated that the fatigue life prediction model can effectively simulate the effects of residual stress, stress concentration, and stress ratio on fatigue damage for post‐impacted thin sheet aluminium alloy materials.

“…Several studies have addressed the interaction between welding residual stresses and fatigue crack initiation and growth. [5][6][7][8] Nevertheless, a better understanding of the welding residual stresses build up and of their interaction with the hydraulic load applied on the turbine requires the development of appropriate numerical tools. Once developed, these tools can be used to simulate the welding operations and to model the associated solid-state phase transformations the material undergoes.…”

Fatigue damage is commonly encountered by operators of Francis type hydraulic turbine runners made of 13Cr-4Ni soft martensitic stainless steel. These large and complex welded casting assemblies are subjected to fatigue crack initiation and growth in the vicinity of their welded regions. It is well known that fatigue behavior is influenced by residual stresses and the microstructure. By including solid-state phase transformation models in welding simulations, phase distribution can be evaluated along with their respective volumetric change and their effect on residual stresses. Thus, it enables the assessment of welding process on fatigue crack behavior by numerical methods. This paper focuses on modeling solid-state phase transformations of 13Cr-4Ni soft martensitic stainless steel, used for manufacturing hydraulic turbine runners, occurring upon welding. It proposes to determine the material parameters of the models for both the austenitic and the martensitic transformation by nonisothermal dilatometry tests. The experiments are conducted in a quenching dilatometer with applied thermal conditions as experienced in the heat-affected zone of homogeneous welds. The activation energy and the kinetic parameters of the austenitic transformation from fully martensitic state are measured from the experimental results. The martensitic transformation modeling from a fully austenitic domain is also presented.
