本文引入了一个离散的反应扩散力学(dRDM)模型来研究形变对反应扩散(RD)过程的影响。dRDM框架采用FitzHugh-Nagumo型RD模型耦合到质量-晶格模型,该模型经历有限变形。dRDM模型描述了一种材料,其弹性性质由有限变形的广义胡克定律(Seth材料)描述。在数值上,dRDM方法结合了有限差分法的RD方程的质量-晶格系统的方程的Verlet积分方案。使用这个框架的结果被复制的自组织起搏活动,已经发现了一个连续的RD力学模型。确定的机制,确定期间的起搏器和它的依赖性的中等大小。最后,它是如何在RDM系统中的起搏器的漂移方向有关的空间分布的变形和曲率效应。
This article introduces a discrete reaction-diffusion-mechanics (dRDM) model to study the effects of deformation on reaction-diffusion (RD) processes. The dRDM framework employs a FitzHugh-Nagumo type RD model coupled to a mass-lattice model, that undergoes finite deformations. The dRDM model describes a material whose elastic properties are described by a generalized Hooke's law for finite deformations (Seth material). Numerically, the dRDM approach combines a finite difference approach for the RD equations with a Verlet integration scheme for the equations of the mass-lattice system. Using this framework results were reproduced on self-organized pacemaking activity that have been previously found with a continuous RD mechanics model. Mechanisms that determine the period of pacemakers and its dependency on the medium size are identified. Finally it is shown how the drift direction of pacemakers in RDM systems is related to the spatial distribution of deformation and curvature effects.
