Abstract
Porous titanium based implants have found various use in dental implants, tissue and bone regeneration. In the present paper, a method of generating models of porous titanium material has been developed from micro-computed tomography radiograph images. Images are processed and three solid models are generated for analysis. To observe the stress contour and the failure initiation at micro level, a method of submodeling has been employed to investigate the effect of loading on the micro-computed tomography based models kept at the centre of a global model of near equivalent porosity. Equivalent, shear and normal stress profiles on the generated model have been analysed to quantify the variation of stress-strain nature and to predict the nature of failure at the micro-porous localized regions due to cyclic nature of loading. Additionally, the average wall shear stress of one of the scaffolds has been determined using Computational Fluid Dynamics analysis at three different inlet velocities.
