软细胞系统准静态流变学的细胞Potts模型
Quasistatic rheology of soft cellular systems using Cellular Potts Model
摘要：
软细胞系统，如泡沫或生物组织，表现出高度复杂的流变性能，即使在准静态制度，数值模拟可以帮助理解。我们提出了一个数值实现内广泛使用的细胞Potts模型的准静态应变。通过模拟准静态应变二维干泡沫，有序和无序的方法的准确性进行了测试。准静态应变在CPM中的实现允许调查复杂的应力-应变关系和细胞系统中发生的结构变化之间的相互作用。
英文摘要：
Soft cellular systems, such as foams or biological tissues, exhibit highly complex rheological properties, even in the quasistatic regime, that numerical modeling can help to apprehend. We present a numerical implementation of quasistatic strain within the widely used cellular Potts model. The accuracy of the method is tested by simulating the quasistatic strain 2D dry foams, both ordered and disordered. The implementation of quasistatic strain in CPM allows the investigation of sophisticated interplays between stress-strain relationship and structural changes that take place in cellular systems.
