Finite element human body models (FEHBMs) are nowadays commonly used to simulate pre- and in-crash occupant response in order to develop advanced safety systems. In this study, a biofidelic model for adipose tissue is developed for this application. It is a nonlinear viscoelastic model based on the Reese et al.'s formulation. The model is formulated in a large strain framework and applied for finite element (FE) simulation of two types of experiments: rheological experiments and ramped-displacement experiments. The adipose tissue behavior in both experiments is represented well by this model. It indicates the capability of the model to be used in large deformation and wide range of strain rates for application in human body models.
有限元人体模型(FEHBMs)如今常用于模拟碰撞前和碰撞时乘员的响应,以开发先进的安全系统。在本研究中,针对该应用开发了一种用于脂肪组织的生物逼真模型。它是一个基于里斯等人公式的非线性粘弹性模型。该模型在大应变框架下制定,并应用于两种类型实验的有限元(FE)模拟:流变实验和斜坡位移实验。该模型很好地再现了这两种实验中脂肪组织的行为。这表明该模型有能力用于大变形和宽应变率范围,以应用于人体模型。
