Mechanics of Bone-substituting Meta-biomaterials

Author Seyed Mohammad AHMADI Abstract One of the main functions of bone is to support the human body mechanically. To fulfil its complex role, bone possesses unique mechanical properties: it is stiff enough to resist deformation while being able to absorb energy. Looking at bone at the macroscopic scale, two distinct types of tissues are …

Isolated and modulated effects of topology and material type on the mechanical properties of additively manufactured porous biomaterials

Authors R. Hedayati, S.M. Ahmadi, K. Lietaert, B. Pouran, Y. Li, Harrie Weinans, C.D. Rans, A.A. Zadpoor Abstract Additive manufacturing (AM) techniques offer the possibility to produce open-cell porous implants with the desired topological design at the micro-scale. The vast majority of previous theoretical and numerical studies carried out on the mechanical properties of AM …

Fatigue performance of additively manufactured meta- biomaterials: the effects of topology and material type

Authors  S.M. Ahmadi, R. Hedayati, Y. Li, K. Lietaert, A. Fatemi, C.D. Rans, B. Pouran, H. Weinans, A.A. Zadpoor Abstract Additive manufacturing (AM) techniques enable fabrication of bone-mimicking meta-biomaterials with unprecedented combinations of topological, mechanical, and mass transport properties. The mechanical performance of AM meta-biomaterials are direct function of their topological design. It is, however, …

Additively Manufactured Open-Cell Porous Biomaterials Made from Six Different Space-Filling Unit Cells: The Mechanical and Morphological Properties

Authors Seyed Mohammad Ahmadi, Saber Amin Yavari, Ruebn Wauthle, Behdad Pouran, Jan Schrooten, Harrie Weinans 1,3 and Amir A. Zadpoor Abstract It is known that the mechanical properties of bone-mimicking porous biomaterials are a function of the morphological properties of the porous structure, including the configuration and size of the repeating unit cell from which …
