A selective strategy for determining suitable structure and fatigue behavior study of minimal surface scaffolds fabricated by EBM

Fei Liu et al.

Summary: This work presents a selective strategy to determine the shape and fatigue life of implanted scaffolds, meeting the requirements of long-term bone implantation. Scaffolds were designed using a novel mathematical method and fabricated using additive manufacturing EBM with Ti-6Al-4V. The failure mechanism of the scaffolds under high cycle fatigue was investigated using Micro-CT, FEA, and SEM, and it was found that scaffolds with larger unit sizes can improve fatigue life without reducing the porosity.

Fatigue behaviour of titanium scaffolds with hierarchical porosity produced by material extrusion additive manufacturing

Karel Slamecka et al.

Summary: This paper investigates the high-cycle fatigue behavior of novel titanium scaffolds with hierarchical porosity and properties comparable to those of human bone. Surprisingly, scaffolds with an open intrastrand pore network outperform those with compact strands in terms of endurance and fatigue strength. The improved fatigue performance is attributed to fatigue crack growth shielding effects, which reduce crack growth rate, prolong crack path, and increase energy absorption. These hierarchically porous titanium structures prepared by direct ink writing can safely serve under cyclic loading conditions and provide multiple open porosity-related functionalities.

Investigating the Effects of Geometrical Parameters of Re-Entrant Cells of Aluminum 7075-T651 Auxetic Structures on Fatigue Life

Amir Ghiasvand et al.

Summary: This study investigated the effects of internal cell angle (theta) and H/L ratio on the variations of Poisson's ratio and fatigue life of Aluminum 7075-T6 auxetic structures. Numerical simulations and fatigue life predictions were conducted using ABAQUS (version 2022) and MSC Fatigue (version 11.0) software. The results showed that increasing both the H/L ratio and angle theta improved the average value of Poisson's ratio. However, increasing the H/L ratio and theta angle decreased the fatigue life of the structures. The structures with higher auxeticity experienced higher fatigue resistance.

Computational homogenization of fatigue in additively manufactured microlattice structures

F. Mozafari et al.

Summary: A novel computational approach for predicting fatigue crack initiation life in additively manufactured microlattice structures is proposed. The approach uses the concept of (micro)plastic dissipation as the driving factor for modeling fatigue degradation and employs a curve-fitting procedure to calibrate the material constitutive parameters. The model's predictive capabilities are verified by comparing the simulation results with experimental fatigue data, and it is shown to be applicable to technologically relevant microlattices with complex microstructure topologies.

L. Boniotti et al.

Summary: This study investigates the fatigue behavior of two strut-based topologies of micro-lattice materials, with a specific focus on the damage evolution during fatigue life. Experimental tests are conducted on micro-lattice specimens under different stress ratios, and a methodological approach for metal foams is adopted to analyze the test results and characterize the fatigue damage evolution. The results show that the finite element model based on the manufactured geometry and the use of a suitable multiaxial fatigue criterion are effective in predicting the location of fatigue failure.
