A new finite element fatigue modeling approach for life scatter in tensile steel specimens

Experimental and numerical investigation of fatigue of thin tensile specimen

“…The experimental results provide an S-N curve for the material and indicate that for 304 SS the mechanism of failure is predominantly transgranular with non-planar crack paths. The numerical aspect extends a previous 2D modeling approach [22] to 3D to provide a phenomenological tool for engineering analysis that accurately captures the observed fatigue failure. A finite element model of tensile specimen was developed to investigate fatigue damage and to account for the effects of topological randomness of material microstructure on fatigue.…”

“…Raje et al [20,21] proposed a model for rolling contact fatigue of bearings using the discrete element method. Recently, Warhadpande et al [22] used a similar approach in a finite element damage mechanics framework and presented a model for life scatter in tensile steel specimens. They used CDM and a 2D material microstructure to investigate intergranular fatigue damage initiation, propagation, and life scatter.…”

Fracture analysis of Kevlar-49/epoxy and e-glass/epoxy doublers for reinforcement of cracked aluminum plates

“…Damage of the joint is evaluated by monitoring stiffness and a damage variable (D) was adopted as [22] ( 4) where E, E′ refer to the original and current Young's Modulus, respectively. D is set as zero when there is no crack present.…”

Effect Of The Spacing Between Submicroscopic Oxide Impurities On The Fatigue Strength Of Structural Steel

“…Those algorithms rely on non-destructive tests (NDT) such as ultrasound or radiological examinations. Processes that influence the structural properties of materials are modeled [2][3]. The strength of structural materials can also be assessed based on other tests that do not cause damage to the examined parts, such as hardness tests.…”
