“… Diseases: In elderly human beings' different type of diseases related to femur bone occurs due to low energy levels. Some of the diseases are discussed below [6].  Osteolysis: In this disease the loss of local bone tissue takes place due to loss of calcium or it may be due to infectious, congenital and movement problems.…”

The main objective of this paper is to study the development of research work performed for femur bone. A broad literature survey from 1980 to 2019 was studied. It was observed that researcher had performed modal analysis, strength analysis and fracture study of femur bone in previous study. The natural frequencies were determined and different mode shapes were studied. The bone materials and different boundary conditions of previous study were noted and future research problems was identified. In conclusion from previous studies it was noted that there is lot of scope to perform study on femur bone. These studies will be related to fracture identification, healing of femur bone and advanced strength analysis for varying bone size using different boundary conditions. For surgical implants few new materials are identified that can be used for future study.

“…These factors have important influence on biodynamic characteristics of spine. For example, for a seated human, an accurate model of the buttocks is required for accurately assessing the transmissibility through the entire body . Moreover, the muscle reaction activity in biodynamic response is very important .…”

The aim of this study is to model the computational model of seated whole human body including skeleton, muscle, viscera, ligament, intervertebral disc, and skin to predict effect of the factors (sitting postures, muscle and skin, buttocks, viscera, arms, gravity, and boundary conditions) on the biodynamic characteristics of spine. Two finite element models of seated whole body and a large number of finite element models of different ligamentous motion segments were developed and validated. Static, modal, and transient dynamic analyses were performed. The predicted vertical resonant frequency of seated body model was in the range of vertical natural frequency of 4 to 7 Hz. Muscle, buttocks, viscera, and the boundary conditions of buttocks have influence on the vertical resonant frequency of spine. Muscle played a very important role in biodynamic response of spine. Compared with the vertical posture, the posture of lean forward or backward led to an increase in stress on anterior or lateral posterior of lumbar intervertebral discs. This indicated that keeping correct posture could reduce the injury of vibration on lumbar intervertebral disc under whole-body vibration. The driving posture not only reduced the load of spine but also increased the resonant frequency of spine.

In this paper, a comparison between two different formulations of elastic splines is made. The two methods under investigation are based on the Bézier and Hermite interpolants. The strategies have been implemented and compared using two simulation cases involving medium and large deflections of a slender element. The investigation has been carried out considering the same number of degrees of freedom, and the two approaches have been compared in terms of complexity, accuracy and robustness. Both methods have also been compared with nonlinear finite element models.
