Voxel-Based Finite Element Simulation of Craniocerebral Traumas

摘要

Modelling of the biomechanics processes is connected with the consideration of objects with a complex shape and the need to build boundaries describing the inner structure of biological tissues. To make the computational experiment closer to the reality, the use of the algorithms for building finite element models utilizing directly the tomography data is preferable. In the present paper we review known mathematical models of a human head, which are used in the problems of contact biomechanics. The validation of the developed finite element model has been conducted for the case of a short duration impact. Computational experiments have been carried out for establishing critical values of a contact force leading to severe injuries.
