The eigen-solution for the micro-structure and macro-structure in non-Newtonian material

The research on the theory and application for the complex non-Newtonian properties in various testing conditions have been interesting and difficult problems, especially in the auto-crash safety engineering process. The interface structure change is concentrated at the boundary-layer leaving other part nearly unchanged. It proves the important property for the contact interface eigen-solution in the energy absorbing principal for the materials structure. It also agrees with the macro-solution in nature in the material world. In this paper, we use FEM to simulate the deformation of honeycomb (HC) structure under the condition of compression and contact to understand the related eigen-solution. After detailed analysis we may summarize the eigen-solution of the deformation. The figures show that, with different impact conditions, the honeycomb could absorb the energy by deforming the contact interface, while part of the structure that distant from the contact interface remain stable. This is consistent with the boundary-layer analysis and stochastic analysis in our previous papers.
