This book aims to simulate some common medical problems using finite element advanced technologies, which establish a base for medical researchers to conduct further investigations. This book consists of four main parts: (1) bone, (2) soft tissues, (3) joints, and (4) implants. Each part starts with the structure and function of the biology and then follows the corresponding finite element advanced features, such as anisotropic nonlinear material, multidimensional interpolation, XFEM, fiber enhancement, UserHyper, porous media, wear, and crack growth fatigue analysis. The final section presents some specific biomedical problems, such as abdominal aortic aneurysm, intervertebral disc, head impact, knee contact, and SMA cardiovascular stent. All modeling files are attached in the appendixes of the book. This book will be helpful to graduate students and researchers in the biomedical field who engage in simulations of biomedical problems. The book also provides all readers with a better understanding of current advanced finite element technologies.

This book was released on 2017-09-22 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic Finite Element Method as Applied to Injury Biomechanics provides a unique introduction to finite element methods. Unlike other books on the topic, this comprehensive reference teaches readers to develop a finite element model from the beginning, including all the appropriate theories that are needed throughout the model development process. In addition, the book focuses on how to apply material properties and loading conditions to the model, how to arrange the information in the order of head, neck, upper torso and upper extremity, lower torso and pelvis and lower extremity. The book covers scaling from one body size to the other, parametric modeling and joint positioning, and is an ideal text for teaching, further reading and for its unique application to injury biomechanics. With over 25 years of experience of developing finite element models, the author's experience with tissue level injury threshold instead of external loading conditions provides a guide to the "do’s and dont's" of using finite element method to study injury biomechanics. Covers the fundamentals and applications of the finite element method in injury biomechanics Teaches readers model development through a hands-on approach that is ideal for students and researchers Includes different modeling schemes used to model different parts of the body, including related constitutive laws and associated material properties

This book was released on 2012 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The femur is the longest limb bone found in humans. Almost all the long limb bones found in terrestrial mammals, including the femur studied herein, have been observed to be loaded in bending and are curved longitudinally. The curvature in these long bones increases the bending stress developed in the bone, potentially reducing the bone's load carrying capacity, i.e. its mechanical strength. Therefore, bone curvature poses a paradox in terms of the mechanical function of long limb bones. The aim of this study is to investigate and explain the role of longitudinal bone curvature in the design of long bones. In particular, it has been hypothesized that curvature of long bones results in a trade-off between the bone's mechanical strength and its bending predictability. This thesis employs finite element analysis of human femora to address this issue. Simplified human femora with different curvatures were modeled and analyzed using ANSYS Workbench finite element analysis software. The results obtained are compared between different curvatures including a straight bone. We examined how the bone curvature affects the bending predictability and load carrying capacity of bones. Results were post processed to yield probability density functions (PDFs) for circumferential location of maximum equivalent stress for various bone curvatures to assess the bending predictability of bones. To validate our findings on the geometrically simplified ANSYS Workbench femur models, a digitally reconstructed femur model from a CT scan of a real human femur was employed. For this model we performed finite element analysis in the FEA tool, Strand7, executing multiple simulations for different load cases. The results from the CT scanned femur model and those from the CAD femur model were then compared. We found general agreement in trends but some quantitative differences most likely due to the geometric differences between the digitally reconstructed femur model and the simplified CAD models. As postulated by others, our results support the hypothesis that the bone curvature is a trade-off between the bone strength and its bending predictability. Bone curvature increases bending predictability at the expense of load carrying capacity.

Available in PDF, EPUB and Kindle. Book excerpt: On a macro-structural level, the bones of the human skeleton is comprised mainly of trabecular (spongy) and cortical bone (dense). Trabecular bone typically occurs at the end points of long bones and has a structure described as a network of plates and rods. Cortical bone forms the hard outer shell and comprised mainly of osteons called Haversian systems. Bone is a composite material consisting mainly of an organic collagenous matrix ad carbonated apatite crystals. The structure of bone material is hierarchically organised and the inhomogeneous nature of bone material results in anisotropic mechanical properties. Bone adapts to its loading history and undergoes hypertrophy as result of increased loading and atrophy when loading is significantly reduced or completely removed. Osteoporosis is a disease of the bone which is characterised by loss of bone material and hence weakening of the bone. As a result of this, osteoporotic bone is more likely to fracture as a result of everyday loading. In this study three-dimensional finite element models of the shaft of the tibia were developed using the ABAQUS (Simula) finite element modelling programme. Models were developed to represent three symptoms of osteoporosis - bone thinning, low density and increased porosity. The models were subjected to compressive and torsional loading, and the stress distribution in response to these loads was analysed to gain an understanding of what areas of the tibia are at greatest risk of fracture and under what loading conditions. A risk of fracture for each of the elements was calculated and the maximum risk of fracture in each model gave an indication of fracture likelihood. This study found that osteoporotic bone showed increased stress and risk of fracture in both compression and torsion. However, torsion of bone with increased porosity was the only combination that produced results that indicate the occurrence of fracture. The aim is for the bone models developed in this study to be used clinically to reduce fracture occurrence in patients with osteoporotic bone loss.

This book was released on 2008 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capabilities of software for solid modeling and finite element analysis have been investigated as they are applied in the modeling and analyzing of bone structure. After conducting a CT scan and importing the data into an automatic mesh generator, a computer model of a bovine tibia was made and static finite element analysis was done to simulate bending. The study evaluated the accuracy of the software to produce a valid representation of the bone, and the extent of user intervention needed to adequately improve the quality of the computer model. The material properties of the bone model were adjusted, using 1, 3, 5, and 8 material definitions for the bone. Each material definition was determined from a range of density values that were extracted from the initial CT scan. Different types of meshes were tested, using quadratic elements with the four material assignments, as well as hexahedral mesh with a single material assignment. The maximum displacement in the transverse direction and maximum stress in the direction of the long axis were then measured and compared for each of the nine models.
