Abstract

A Mullins effect is a commonly observed phenomenon describing how biological tissues lose their elastic modulus encountering a certain level of deformation. Many biological tissues, including heart, skin, and blood vessels, exhibit this stress-softening phenomenon. The current study models and simulates such an effect using skin samples from male and female mice tested under higher cyclic loading conditions. The study employs a newly proposed energy density function and compares its performance against existing energy functions that fail to accurately predict the Mullins effect at higher loading cycles. The findings, supported by experimental data, demonstrate that the proposed energy function qualitatively captures the effect in the tested skin samples.
穆林斯效应是一种普遍观察到的现象,描述了生物组织在遇到一定程度的变形时如何失去弹性模量。包括心脏、皮肤和血管在内的许多生物组织都表现出这种应力软化现象。本研究利用在较高循环加载条件下测试的雄性和雌性小鼠皮肤样本,对这种效应进行建模和模拟。该研究采用了一种新提出的能量密度函数,并将其性能与现有的能量函数进行了比较,现有的能量函数无法准确预测较高加载周期下的穆林斯效应。研究结果得到了实验数据的支持,证明所提出的能量函数能够定性地捕捉到测试皮肤样本中的效应。

期刊介绍: Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
