| contents | Trabecular bone modeling methodology using geometric representations Osvaldo Ruiz-Cervantes José Salvador Lara-Ramírez Edgar Isaac Ramírez-Díaz Armando Ortiz-Prado Ingeniería bone modeling Cancellous bone trabecular structure ęnite element software In this paper is presented a methodology to generate two-dimensional models of cancellous bone from images, with the main objective to achieve a closer representation to reality, in terms of the geometries that can be obtained. The methodology mainly uses Python™ language programming to establish instructions for using Abaqus™ graphical tools and therefore automatically generate the trabecular structure from the original image. As a ęrst step, each tra - becula of the image is idealized as an ellipse and each one is taken as basis for generating the geometries of pores and trabeculae in the model. A simulation of a compression test is also presented for three models made with this methodology, where ęnite element software was used. It is concluded that the methodology allows geing a very similar trabecular structure to the real one. 2017 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40453343003 en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
