Findings

Identified regions of maximum stress in the arm under various conditions.

Provided insights into injury-prone areas of the human arm.

Demonstrated the effectiveness of CT-based finite element modeling.

Abstract

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.
