ST-01-01  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Civil Engineering   aThesis (M.Eng.) - Asian Institute of Technology, 2001  aIn the thesis, formulation of two different shell elements, which are a c0 Degenerated Composite Shell Element and a Four-Noded Quadrilateral c° Composite Shell Element Based on Assumed Strain Fields, is presented. The elements are tested through several numerical examples and the results are presented. The c0 Degenerated Composite Shell Element, in a combination with standard 8-noded solid elements, are used to model a composite sandwich plank with several potential engineering uses including light-weight structures and foundations and temporary coverings for use in roadway repair. A finite element model of the plank is presented and used in a numerical analysis to compute displacements and stresses. Deflections of the plank are compared to those of the equivalent weight I-beams. The stress distribution pattern of the plank is also compared to those of equivalent weight I-beams and to those of an isotropic, aluminum plank of the same geometry. Discussions are made on results obtained from the analysis and recommendations for future studies are discussed.  0aSandwich construction 0aFinite element method1 aBarry, William Joseph,eChairperson0 aWorsak Kanok-Nukulchai,eExamination Committee1 aKim, Kidu,eExamination Committee2 aAsian Institute of Technology Partial Scholarship, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
