Available in PDF, EPUB and Kindle. Book excerpt: The development of layered finite elements has facilitated analysis of laminated composite structures. However, the analysis of a structure containing both isotropic and composite materials remains a difficult problem. A methodology has been developed to conduct a ''global-local'' finite element analysis. A ''global'' analysis of the entire structure is conducted at the appropriate loads with the composite portions replaced with an orthotropic material of equivalent materials properties. A ''local'' layered composite analysis is then conducted on the region of interest. The displacement results from the ''global'' analysis are used as loads to the ''local'' analysis. the laminate stresses and strains can then be examined and failure criteria evaluated.
