Most work done in this area has adopted isotropic assignment strategy as its simplicity. However, bone material is widely recognized as being anisotropic rather than isotropic. Therefore, this work is aimed to simulate the inhomogeneity and anisotropy of femur by assigning each element of the mesh model the material properties with a numerical integration method and properly defining the principal material orientation, and then compare the biomechanical analysis results of isotropic model with that of anisotropic model under six different loading conditions. Based on the analysis results of the equivalent Von Mises stress and the nodal displacement, four different regions of interest are chosen to achieve this comparison. The results show that significant differences between the two material property assignments exist in the regions where anisotropic material property is sensitive to orientation definition. Thus, orientation definition is important to finite element simulation of bone material properties.","license":"You are licensing your work to Kitware Inc. under the\nCreative Commons Attribution License Version 3.0.\n\nKitware Inc. agrees to the following:\n\nKitware is free\n * to copy, distribute, display, and perform the work\n * to make derivative works\n * to make commercial use of the work\n\nUnder the following conditions:\n\\\"by Attribution\\\" - Kitware must attribute the work in the manner specified by the author or licensor.\n\n * For any reuse or distribution, they must make clear to others the license terms of this work.\n * Any of these conditions can be waived if they get permission from the copyright holder.\n\nYour fair use and other rights are in no way affected by the above.\n\nThis is a human-readable summary of the Legal Code (the full license) available at\nhttp://creativecommons.org/licenses/by/3.0/legalcode","keywords":["Inhomogeneity","Material properties","Finite element analysis","Orientation definition","Anisotropy"],"authors":[{"name":"Yang, Haisheng","email":"hs.yang@siat.ac.cn","affiliations":[]},{"name":"Guo, Tongtong","affiliations":[],"corresponding":true},{"name":"Ma, Xin","affiliations":[],"corresponding":true}],"date_submitted":"2008-05-30T08:58:52Z","external_publication_id":561,"revision_cids":["bafkreib6v2o4bl5poila2arnlmtdxpwbhu7tkwlyen3cvnlwafxtjlvwgq"]},"mdast":{"type":"root"},"downloads":[{"url":"https://ipfs.desci.com/ipfs/bafkreigxbqgcnru47sztig6ahhitvnz5caxisxh63ftsmlih4f6qmjdgfu","title":"root/reviews.md","filename":"reviews.md","extra":{"size_bytes":3778,"type":"file"}},{"url":"https://ipfs.desci.com/ipfs/bafkreidlfx3r6ary5a55f2ann75a3djz267idjuturonevegqobymfin4u","title":"root/insight-journal-metadata.json","filename":"insight-journal-metadata.json","extra":{"size_bytes":11913,"type":"file"}},{"url":"https://dweb.link/ipfs/bafkreiem3zmljhq6dgdhbkygyjsxabiacvogils3xpiuvxya27naeh3kvu","title":"root/article.pdf","filename":"article.pdf","extra":{"size_bytes":292009,"type":"file"}}],"references":{"cite":{"order":["ref1","ref2","ref3","ref4","ref5","ref6","ref7","ref8","ref9","ref10","ref11","ref12","ref13"]},"data":{"ref1":{"label":"ref1","enumerator":"1","url":"https://doi.org/10.1016/s0021-9290(01)00204-4","html":"A contact model with ingrowth control for bone remodeling around cementless stems+Journal of Biomechanics+35+167+176+2002+P.R.
