Hierarchical Strategy for Analysis of Materials withComplex Microstructure

摘要

An earlier work introduced a new strategy where the natural hierarchicalcharacter of model descriptions and simulation results are exploited to expediteanalysis of problems. Hierarchical techniques were used in the development,organization, and management of finite element models, and for the post-processingof the results from the analyses. In the current work, the hierarchical strategy isused to analyze materials that have complex microstructure. The hierarchicalanalysis environment is used to analyze a Double Cantilever Beam (DCB) specimenfabricated with woven composite. Such a configuration contains manymicrostructural scales such as fiber/matrix, tow architecture and laminate. Theresults of a detailed finite element stress analysis on the DCB specimen arepresented.
