The Mullins Effect in Hyperelastic Materials

该研究旨在建立一个模拟Mullins效应的本构模型，Mullins效应是弹性体和软体生物组织在反复加载和卸载时观察到的一种非线性应力软化现象。将分析研究应力软化的静态和动态效应，以提供与手术气球使用中遇到的困难相关的现象的见解，以增强对应力软化弹性体材料特性的理解，并在一些有用的技术应用中研究穆林斯效应。实验工作与建模和应用问题的相关性的平衡是优秀的。该研究方法新颖，可能产生具有重要工程意义的结果。＊＊＊

Beatty 9634817 The proposed research is aimed at developing a constitutive model for modeling the Mullins effect, a nonlinear stress softening phenomenon observed in elastomers and soft biological tissues subjected to repeated loading and unloading. Both static and dynamic effects of stress softening will be studied analytically to provide insight to phenomena related to difficulties encountered in use of surgical balloons, to enhance understanding of the material properties of stress softened elastomers and to investigate the Mullins effect in some useful technical applications. The balance of experimental work with modeling and relevance to applied problems is excellent. The research approach is novel and likely to yield results of significant engineering importance. ***
