The local response in structures using the Embedded Unit Cell Approach

摘要: Development of a new concept, the embedded unit cell (EUC) approach.The EUC formulation is not restricted to homogenization periodic assumptions.Solution stress concentration problems through classical formulation.The reduced computational cost model. This paper presents development Embedded Unit Cell approach, calculate local responses in elastic media. The approach based on multi-scale non-periodic domains evaluate local/micro response where concentrations are expected. alternative boundary conditions which assumptions that required theory. provides model macroscopic/global problem while preserving accuracy at microscale problem. We conclude with numerical verification study.
