Multiscale mechanics of macromolecular materials with unfolding domains
摘要:
我们提出了一个通用的多尺度方法的力学行为的三维网络的大分子进行应变诱导展开。从一个(基于统计的)能量分析的大分子展开策略,我们得到一个三维连续模型与可变的自然配置和能量函数解析推导出的微尺度材料参数。与实验的比较表明,该模型的能力来描述复杂的行为,与残余拉伸和展开的影响,观察到在不同的生物材料。
英文摘要:
We propose a general multiscale approach for the mechanical behavior of three-dimensional networks of macromolecules undergoing strain-induced unfolding. Starting from a (statistically based) energetic analysis of the macromolecule unfolding strategy, we obtain a three-dimensional continuum model with variable natural configuration and an energy function analytically deduced from the microscale material parameters. The comparison with the experiments shows the ability of the model to describe the complex behavior, with residual stretches and unfolding effects, observed in different biological materials.
