Abstract : The subject effort, Turbine Engine Component Analysis, has as its objective the development and demonstration of in-house capabilities for computerized structural analyses of turbine engine components. Phase II, Structural Analysis, consists of a series of eight Tasks. This report describes work performed under Task 1, Cantilevered Composite Flat Plate Analysis. The selected structure, a cantilevered composite flat plate subjected to a pressure load, is ideally suited for meeting the Task primary objective which is to demonstrate the plate and shell analysis capabilities of three computer codes used for engine blade-type structure. A second objective is to ensure that the various analysis programs, file transfer procedures, and data manipulation codes are fully operational and compatible. Twelve plate configurations are analyzed using three different finite element analysis codes: ADINA, COSMIC NASTRAN, and MAGNA. Results are compared with theoretical values to verify the finite element codes and the modeling assumptions.
