69 Flexural Analysis of 3D Braided Composite Plates Subjected to Lateral Loads Masoud Mahrughi m mahrughi@me iut ac ir Date of Submission 2014 12 9 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Hamid Reza Mirdamadi hrmirdamadi@cc iut ac irAbstract In this article a novel micro macromechanical theory is proposed for flexural analysis of 3D braidedrectangular plate subjected to lateral loads This theory is based on a novel micromechanical equivalentlayerwised multi unit cell combined with macromechanical full layerwise theory so called equivalent fulllayerwise multi unit cell theory EFL MUC A 3D braided composite is considered as a cell system whereelastic properties of each cell depend on the position of cell in cross section Instead of acquiring the globalelastic constants of 3D braided three theoretical layers layers are established and the elastic constants ofeach layer are acquired separately This micromechanical procedure makes this model in agreement withmacromechanical full layerwise theory Based on this theory the governing differential equations are derivedfor flexural analysis of rectangular 3D braided plate subjected to lateral loads The problem is solved withGalerkin and finite element method A MATLAB code is developed and the stress components in 3D braidedplate subjected to lateral load solved by EFL MUC theory are calculated throughout the plate only byinserting the fundamental properties of matrix fiber and geometrical properties of a 3D braided compositesystem The stress distribution in 3D braided composite plates solved by EFL MUC theory seems quitedifferent from that of isotropic plates solved by equivalent single layer theories The differences will bediscussed in this thesis Furthermore after establishing equivalents and volume averaging throughout 3Dbraided composite the micromechanical results of EFL MUC are compared with experimental and those ofother researches in the field Keywords 3D braided composite plate equivalent full layerwise milti unit cell theory flexuralanalysis lateral load
