Analysis of Stress and Strain of Human Skull Bone in Physical Injury

The human brain is the most vital organ and the body’s command center. As a result, its protection is essential. This paper aims to simulate the impact of an object colliding with a rigid plate on the human skull bone using Visco-elastic analysis. Abaqus software can be used to compute the stresses associated with all parts of the sphere after hitting a rigid object with the Von-Mises criterion and construct and evaluate the energy-strain diagram in terms of time. The stresses in question can be measured and compared between different materials in different parts of the solid isotropic sphere by changing the material with the highest toughness. Furthermore, the stress and strain energy obtained in various parts of the object over time are compared to the stress and strain energy at the moment of collision; then, for each of the materials, the velocity parameter is changed, and the effect of velocity on the stresses and strain energy of the object is investigated. Strain energies and stresses in all materials on all object parts are reduced to zero after the collision. Finally, as the velocity parameter increases, the stresses induced by the object’s collision are valid for all materials.
