植物细胞壁的微观结构由嵌入细胞壁基质中的纤维素微纤丝给出。在本文中,我们考虑一个微观模型的粘弹性变形的植物细胞壁和化学过程中的细胞壁基质之间的相互作用。我们认为弹性变形的细胞壁微纤维和粘弹性Kelvin-Voigt型变形的细胞壁矩阵。使用均匀化技术(两尺度收敛和周期性展开方法),我们从细胞壁生物力学的微观模型,包括强耦合的线性粘弹性方程和反应扩散和常微分方程系统的宏观方程。作为典型的微观粘弹性问题,宏观方程的粘弹性变形的植物细胞壁包含记忆项。导出了退化粘弹性方程的宏观问题的摄动参数。
The microscopic structure of a plant cell wall is given by cellulose microfibrils embedded in a cell wall matrix. In this paper we consider a microscopic model for interactions between viscoelastic deformations of a plant cell wall and chemical processes in the cell wall matrix. We consider elastic deformations of the cell wall microfibrils and viscoelastic Kelvin–Voigt type deformations of the cell wall matrix. Using homogenization techniques (two-scale convergence and periodic unfolding methods) we derive macroscopic equations from the microscopic model for cell wall biomechanics consisting of strongly coupled equations of linear viscoelasticity and a system of reaction-diffusion and ordinary differential equations. As is typical for microscopic viscoelastic problems, the macroscopic equations governing the viscoelastic deformations of plant cell walls contain memory terms. The derivation of the macroscopic problem for the degenerate viscoelastic equations is conducted using a perturbation argument.
