Procedure for modelling of soft tissues behaviour

The procedural steps for the efficient modelling and simulation of material behavior of human cervical spine ligaments have been presented in the paper. They are based on the mechanical principles incorporated in the material model, suitable for the description of soft tissues behavior. The material parameters set which have to be identified for the presented model has been additionally expanded here to make possible better calibration of the model by the application of genetic algorithm. The genetic algorithm has been recognized in this investigation as an efficient tool to overlap the bridge among the non-linearity of material behavior and material parameters of the chosen model and thus make possible material behavior modelling which follows materials response as accurately as possible. The basic process steps have been developed here for the efficient optimization of soft tissues behavior modelling.
