This study is aimed at setting a method of experimental parameter estimation for large-deforming nonlinear viscoelastic continuous fibre-reinforced composite material model. Specifically, arterial tissue was investigated during experimental research and parameter estimation studies, due to medical, scientific and socio-economic importance of soft tissue research. Using analytical formulations for specimens under combined inflation/extension/torsion on thick-walled cylindrical tubes, in vitro experiments were carried out with fresh sheep arterial segments, and parameter estimation procedures were carried out on experimental data. Model restrictions were pointed out using outcomes from parameter estimation. Needs for further studies that can be developed are discussed.
本研究旨在为大变形非线性粘弹性连续纤维增强复合材料模型设定一种实验参数估计方法。具体而言,由于软组织研究在医学、科学和社会经济方面的重要性,在实验研究和参数估计研究过程中对动脉组织进行了调查。利用厚壁圆柱管在充气/拉伸/扭转联合作用下的试样解析公式,对新鲜绵羊动脉段进行了体外实验,并对实验数据进行了参数估计程序。利用参数估计结果指出了模型的局限性。讨论了可开展的进一步研究的需求。
