In this study, the connection between total strain energy density and fracture surface topography is investigated in additively manufactured maraging steel exposed to low-cycle fatigue loading. The specimens were fabricated using laser beam powder bed fusion (LB-PBF) examined under fully-reversed strain-controlled setup at amplitudes scale from 0.3% 1.0%. post-mortem surfaces explored a non-contact 3D measuring system entire method. focus on relationship characteristics, expressed by density, features, represented areal, volume, fractal dimension factors. A life prediction model based parameters proposed. presented shows good accordance with test results outperforms other existing models density. This can be useful for post-failure analysis of engineering elements fatigue, especially materials produced additive manufacturing (AM).

In this study, fatigue fracture surfaces of aluminium alloy 2017-T4 notched specimens were investigated under cyclic bending to find an alternative failure loading index.. The surface topographies measured on the entire area with optical profilometer for different conditions. Fatigue crack initiation life Ni and total Nf examined using standard topography parameters (such as, root mean square height Sq, arithmetical Sa, maximum Sz) non-standard fractal dimension Df). assessment was successfully performed by combining both stress state features. results show that plane geometry, expressed fractographic-fractal dimension, can facilitate estimation post-failure history.

In this paper, the association between Smith-Watson-Topper (SWT) parameter and fracture surface topography is studied in additively manufactured maraging steel exposed to variable-amplitude fatigue loading. The post-failure surfaces were examined using a non-contact 3D measuring system entire method. focal point on correspondence characteristics, articulate by SWT parameter, features, represented areal, volume, fractal dimension parameters. A life prediction model based factors proposed. presented expresses good compliance with test results. This can be useful for post-mortem analysis of engineering elements under loading fatigue, especially materials produced additive manufacturing (AM).
