A CT image based finite element modelling to predict the mechanical behaviour of human arm

In the present work, complex irregular bones and joints of the complete human arm were developed in a computer-aided design environment. Finite element analysis of an actual human arm was done to identify the distribution of stress using von-Mises stress and maximum principal stress measures. The results obtained from the present study revealed the region where, maximum stress was developed for different loading and boundary conditions with different joint rotations as obtained in the actual human arm. This subject specific analysis helps to analyse the region of the arm in which the risk is more.

Modelling and analysis of biological joints of a human arm in different movements

In the present work, irregular complex joints of the human arm are modelled in the computer-aided design environment. Accurately the geometric models of the joints and surrounding bony regions are developed from computed tomography data set and the range of movements are analysed. In this present work, biological joints are approximated into the mechanical joint without losing any kinematic behaviour and degrees of freedom. Then the analysis is done to determine the importance of joint geometries with different loading and boundary conditions. The present study helps to predict the behavior of joint configuration in the design stage.
