Abstract

The movement of a human arm body is complex since it is composed of an assembly of elements in three-dimensional movement, thus, modeling this arm is required to write its various movements using systems of simple and convergent equations. Therefore, the finite element method is an essential method to write and analyze the different kinematic and dynamic movements of the arm. The position of stress, strains, velocity, and acceleration in the different limbs of the arm have been determined and analyzed. The applications of this topic may have a great importance in the field of biomechanics, especially when the material considered is of the isotropic or orthotropic type. Good comparisons were observed for both types of materials investigated in our research.
