This paper deals with the mechanical characterization of brain tissue which behaves as a viscoelastic material. We focus on the linear viscoelastic behavior, which should apply for small strains at any strain rate, and demonstrate the applicability of the time/temperature superposition principle. This principle allows the opportunity to extend the range of shear rates for which the material is characterized, and makes the results applicable to impact conditions. This characterization of the linear behavior forms the basis for a further nonlinear characterization of the tissue.
本文研究了表现为粘弹性材料的脑组织的力学特性。我们关注线性粘弹性行为，该行为适用于任何应变率下的小应变，并证明了时间/温度叠加原理的适用性。这一原理为扩展材料特性所适用的剪切速率范围提供了机会，并使结果适用于冲击条件。这种线性行为的表征为组织的进一步非线性表征奠定了基础。
