The dynamical behavior and vibrational characteristics of bone and the attached soft tissues, such as natural frequencies are widely used in therapeutic vibrations including the detection of the pain threshold and tissue damage, fracture healing and bone remodeling, and design of implants. Most of studies, have focused on either bone or the soft tissues to investigate the final effects of these treatments. In the present research the vibrational characteristics of combined bone-soft tissues are studied. For this purpose, the bovine tibia and its attached muscles and tendons have been targeted. The experimental results of modal tests were collected and compared with a three-dimensional finite element analysis. Bone was modeled as an inhomogeneous isotropic material. The model includes bone marrow as an isotropic homogeneous material and the attached soft tissues as an incompressible hyperelastic isotropic material. It was found that the inhomogeneity bone and considering bone marrow does not enhance much the model results. The effect of soft tissues on the natural frequencies has shown a reduction of 12% in the first two transverse modes and up to 70% in higher modes. The stiffening effect of soft tissue (due to large deformation) on the as natural frequencies was also investigated. An increase of up to 70% (at some frequencies) was observed in larger deformations.

“…For the creation of the tibia bone model author used computed tomography (CT) images, in this work the researcher are not considered Von misses stress and displacement. Sepehri et al [2] worked on the study of mechanical properties of stress induced tibia bone model. In this work researcher considered only cortical bone but not spongy bone.…”

In this Paper tibia bone is generated and analyzed using finite element method by applying static load on it and various stress concentrated regions in tibia bone is identified and analyzed for stresses at various locations by taking Von Misses stress and displacement. The body of the human being consists of many bones and muscles and many instances, the application of different loads leads to the damage in the bone. So it is necessary to evaluate the effect of applied loads on the bone of human body. In most of the cases whole body weight is carried by the tibia bone which is below the knee roll. So it’s necessary to estimate the strength of the tibia bone to carry the body weight. The behavior of the tibia bone under dynamic and static load is necessary for the orthopedic doctors during the treatment of ankle trauma and fractures, but in this paper the study is limited to only static and find out the aspects like Von Misses stress and displacement of tibia bone model under different forces of 800N, 810N, 820N &830N and from the result its understood that both Von Misses stress and displacement are directly proportional to the applied force and the value of Von misses stress in result is less than the maximum value i.e 18MPa for calcium, hence its concluded that generated bone model can withstand the applied force in the range of 800 to 850N

Biomechanics is the examination of the structure and function of biological systems by means of the methods of mechanics. Finite element analysis is a computer-based numerical analysis method that can be used to calculate the response of a model to a set of well-defined boundary conditions. Although typical analysis methods, FE analysis can be used to analyze structures of complicated geometry and inhomogeneous material properties. The finite element method is an ideal method for analyzing live tissues such as femur bone this is since it has complex geometric shapes and inhomogeneous material properties. The objective of an FE analysis is to find the distribution of an unknown within a body. In this research, a simplified model of the femur with some of the inner structures (trabeculae, Haversian canals, marrow) was designed. After designing, a simplified model, FE analysis, and optimization were done. Obtained results showed that the max stress is 5.2717e8 Pa. It reached 4.5687e8 Pa after optimization of the model.
