This thesis presents the design, analysis and testing of a bone plate for mandibular fracture fixation. Conventional bone plates are commonly used to set fractures of the mandible in a surgical setting. If proper alignment between the two bone segments is not achieved, then a malocclusion can result; this condition often causes significant discomfort to the patient, and may require costly and risky revision surgery to repair. Current methods of bone plate fixation require a surgeon to visually align the segments of bone, and once the plate has been affixed to the bone, there is little that can be done to adjust alignment of the fracture. The modified bone plate presented here has a deformable mid-section, with the purpose of allowing a surgeon to compensate for mis-alignment observed after the plate has been affixed to the fractured bone. The mechanics of deformation associated with various adjustment mechanisms was explored analytically, numerically, and experimentally. It was found that in order to plastically deform the adjustable section, a force of 358.8 N is required, compared with a predicted value of 351 N obtained using numerical simulations and 487 N using a fixed-fixed beam model with a concentrated central load. In addition to static tests, a dynamic testing jig has been designed with the intent of evaluating in vitro performance of the modified bone plate. Current ASTM and ISO standards for bone plate testing require forces to be applied to the faces of the bone plate, orthogonal to the direction of loading experienced in vivo. This condition is applicable to long bones such as the humerus or femur, however loading conditions of the mandible are significantly different. The testing jig allows for any bone plate of any shape to be fixed such that a force can be applied in order to simulate the normal in vivo loading conditions. This system could be used to further optimize the design of current and future deformable bone plates before they are incorporated into invasive animal or clinical trials.

This book provides several applications of the finite element method (FEM) for solving real-world problems. FEM is a widely used technique for numerical simulations in many areas of physics and engineering. It has gained increased popularity over recent years for the solution of complex engineering and science problems. FEM is now a powerful and popular numerical method for solving differential equations, with flexibility in dealing with complex geometric domains and various boundary conditions. The method has a wide range of applications in various branches of engineering such as mechanical engineering, thermal and fluid flows, electromagnetics, business management, and many others. This book describes the development of FEM and discusses and illustrates its specific applications.

​Design of Artificial Human Joints & Organs is intended to present the basics of the normal systems and how, due to aging, diseases or trauma, body parts may need to be replaced with manmade materials. The movement of the body generates forces in various work situations and also internally at various joints, muscles and ligaments. It is essential to figure out the forces, moments, pressure etc to design replacements that manage these stresses without breaking down. The mechanical characterization of the hard and the soft tissues are presented systematically using the principles of solid mechanics. The viscoelastic properties of the tissue will also discussed. This text covers the design science and methodology from concept to blueprint to the final component being replaced. Each chapter will be a brief overview of various joint/organ replacement systems. Engineers working on artificial joints and organs, as well as students of Mechanical Engineering and Biomedical Engineering are the main intended audience, however, the pedagogy is simple enough for those who are learning the subject for the first time.

This book presents the latest developments in the field of biomedical engineering and includes practical solutions and strictly scientific considerations. The development of new methods of treatment, advanced diagnostics or personalized rehabilitation requires close cooperation of experts from many fields, including, among others, medicine, biotechnology and finally biomedical engineering. The latter, combining many fields of science, such as computer science, materials science, biomechanics, electronics not only enables the development and production of modern medical equipment, but also participates in the development of new directions and methods of treatment. The presented monograph is a collection of scientific papers on the use of engineering methods in medicine. The topics of the work include both practical solutions and strictly scientific considerations expanding knowledge about the functioning of the human body. We believe that the presented works will have an impact on the development of the field of science, which is biomedical engineering, constituting a contribution to the discussion on the directions of development of cooperation between doctors, physiotherapists and engineers. We would also like to thank all the people who contributed to the creation of this monograph—both the authors of all the works and those involved in technical works.
