The purpose of this paper is to present a simple new method for calculating the opening angle produced by a given residual stress field in a soft biological tissue. The method uses minimization of potential energy, and is therefore named the MPE method. The accuracy of the MPE method is evaluated by comparing the opening angle it predicts to results from a finite element model of the opening angle experiment. We show that the MPE method provides good predictions of the opening angle, and that it is significantly more accurate than two other methods previously used in the literature.
本文的目的是提出一种简单的新方法,用于计算软生物组织中给定残余应力场产生的开口角度。该方法采用势能最小化,因此被命名为MPE方法。通过将MPE方法预测的开口角度与开口角度实验的有限元模型结果进行比较,评估了MPE方法的准确性。我们表明,MPE方法能够很好地预测开口角度,并且比文献中先前使用的其他两种方法显著更准确。
