THE APPLICABILITY OF THE TIME TEMPERATURE SUPERPOSITION PRINCIPLE TO BRAIN-TISSUE/

This paper deals with the mechanical characterization of brain tissue which behaves as a viscoelastic material. We focus on the linear visco elastic behavior, which should apply for small strains at any strain r ate, and demonstrate the applicability of the time/temperature superpo sition principle, This principle allows the opportunity to extend the range of shear rates for which the material is characterized, and make s the results applicable to impact conditions. This characterization o f the linear behavior forms the basis for a further nonlinear characte rization of the tissue. (C) 1997 Elsevier Science Ltd.
