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.
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.
