WebA fourth-order tensor was introduced in Section 25.2 to represent a multilayer network. Tensor decomposition is an effective tool for multiarray data analysis, and mono-layer centrality measures can be extended in order to identify key nodes in multilayer networks. WebThe stress tensor and strain tensor are both second-order tensor fields, and are related in a general linear elastic material by a fourth-order elasticity tensor field. In detail, the tensor quantifying stress in a 3 …
