Journal ArticleDOI
Additively manufactured metallic porous biomaterials based on minimal surfaces: A unique combination of topological, mechanical, and mass transport properties
F. S. L. Bobbert,Karel Lietaert,Ali Eftekhari,Behdad Pouran,S.M. Ahmadi,Harrie Weinans,Amir A. Zadpoor +6 more
TL;DR: Rationally designed and additively manufactured porous metallic biomaterials based on four different types of triply periodic minimal surfaces that mimic the properties of bone to an unprecedented level of multi-physics detail exhibit an interesting combination of topological, mechanical, and mass transport properties.
Journal ArticleDOI
Mechanical behavior of regular open-cell porous biomaterials made of diamond lattice unit cells
S.M. Ahmadi,Gianni Campoli,S. Amin Yavari,Banafsheh Sajadi,Ruben Wauthle,Jan Schrooten,Harrie Weinans,Harrie Weinans,Amir A. Zadpoor +8 more
TL;DR: New analytical solutions and closed-form relationships for predicting the elastic modulus, Poisson׳s ratio, critical buckling load, and yield (plateau) stress of cellular structures made of the diamond lattice unit cell are presented.
Journal ArticleDOI
Relationship between unit cell type and porosity and the fatigue behavior of selective laser melted meta-biomaterials
S. Amin Yavari,S.M. Ahmadi,R. Wauthle,Behdad Pouran,Jan Schrooten,Harrie Weinans,Harrie Weinans,Amir A. Zadpoor +7 more
TL;DR: It was observed that, in addition to static mechanical properties, the fatigue properties of the porous biomaterials are highly dependent on the type of unit cell as well as on porosity.
Journal ArticleDOI
Additively Manufactured Open-Cell Porous Biomaterials Made from Six Different Space-Filling Unit Cells: The Mechanical and Morphological Properties
S.M. Ahmadi,Saber Amin Yavari,Saber Amin Yavari,R. Wauthle,Behdad Pouran,Behdad Pouran,Jan Schrooten,Harrie Weinans,Harrie Weinans,Amir A. Zadpoor +9 more
TL;DR: This work studied the relationship between relative density (RD) of porous Ti6Al4V EFI alloy and five compressive properties of the material, namely elastic gradient or modulus (Es20–70), first maximum stress, plateau stress, yield stress, and energy absorption.
Journal ArticleDOI
Failure mechanisms of additively manufactured porous biomaterials: Effects of porosity and type of unit cell
Javad Kadkhodapour,Javad Kadkhodapour,H. Montazerian,A. Ch. Darabi,Ali Pourkamali Anaraki,S.M. Ahmadi,Amir A. Zadpoor,Siegfried Schmauder +7 more
TL;DR: The computational models incorporating the Johnson-Cook damage model could predict the plateau stress and maximum stress at the first peak with less than 18% error and the computationally predicted deformation modes were in good agreement with the results of scaling law analysis.
