主 题:mechanical characterization morphology finite element analysis porous iron shear stress permeability
摘 要:Higher strength and lower degradation rate of Fe compared to magnesium and zinc have made it the most reliable for orthopaedic ***,this paper studies the morphological and mechanical characteristics of porous Fe fabricated using subtractive manufacturing for load bearing bone *** types of porous Fe(19%,39%and 59%)were prepared and then modelled into a 3D model for finite element *** mechanical properties evaluated through finite element analysis were then validated by the experimental *** fluid dynamics was done in this study to evaluate the permeability and wall shear stress of the porous *** between morphological indices,mechanical properties,shear stress and permeability were then *** mechanical behaviour of porous Fe investigated through finite element analysis was in good agreement with the experimental *** mechanical properties of porous Fe specimen particularly sample C(modulus:5.63 GPa and yield strength:145.7 MPa)was tailored to the cancellous bone(modulus:0.5 GPa-18 GPa and yield strength:101 MPa-169.6 MPa).As the porosity increased,the performance of porous Fe regarding mechanical properties and morphological properties were enhanced.
