Multiscale modeling of composite materials has become quite popular for analysis of composite structures. Progressive failure analysis of composites is one area where micromechanics based approaches are widely used. Micromechanics approach requires the modeling of the smallest repetitive volume, also called as the Representative Volume Element (RVE), such that volume fraction of the RVE must be in accordance with the volume fraction of the composite material. Current study aims to show both 2D and 3D RVE applications through a complete homogenization process of the 3D model of the unidirectional composite material. Comparisons of the elastic moduli determined by the 2D and 3D RVEs are formed and compared. The applicability of the 2D RVE in micromechanics analysis of a 3D macro structure is investigated.

Design, Modelling and Analysis of Morphing Airfoils Köksal, Buğra; Şahin, Melin; Uzol, Oğuz; Department of Aerospace Engineering (2023-1) This study presents the design, finite element (FE) modeling and analysis of a morphing airfoil using pressure-actuated cell structures. It is aimed that the selected baseline airfoil should be capable of changing its profile to morph into a target airfoil profile. To achieve this goal, first, a NACA 0012 airfoil with a 500 mm chord and 8 mm x 8 mm outer cross-section is obtained in Altair® HyperWorks environment as a baseline airfoil. Following this, the cell actuators responsible for morphing are designed...
Structural Coupling of Two Nonlinear Structures Tepe, Çağrı; Ciğeroğlu, Ender (null; 2015-02-02) In mechanical design, modeling and analysis of a complex structure can be simplified with dividing the structure into substructures; therefore, any change in the structure can be addressed easily which is referred as “structural coupling”. Utilization of proper coupling techniques, it is possible to understand the behavior of the whole structure by considering the behavior of its substructures. For linear structures, coupling is a common technique; however, in most of the engineering structures, nonlinearit...
Coarse-to-fine surface reconstruction from silhouettes and range data using mesh deformation Sahillioğlu, Yusuf; Yemez, Y. (2010-03-01) We present a coarse-to-fine surface reconstruction method based on mesh deformation to build watertight surface models of complex objects from their silhouettes and range data. The deformable mesh, which initially represents the object visual hull, is iteratively displaced towards the triangulated range surface using the line-of-sight information. Each iteration of the deformation algorithm involves smoothing and restructuring operations to regularize the surface evolution process. We define a non-shrinking...
Analysis and design of conformal frequency selective surfaces / Dalkılıç, Akın; Alatan, Lale; Department of Electrical and Electronics Engineering (2014) An efficient analysis and design approach for conformal frequency selective surface (FSS) structures is developed. The design methodology involves the analysis of both the planar and curved FSS structures. First, planar unit cell analysis of conformal FSS models are accomplished for normal and oblique incidence cases. To prove conformal applicability of planar designs, a semi-finite analysis method is utilized. This method is based on solution of a singly periodic curved FSS structure of semi-cylinder shape...
Validation of 3D finite element solution for laterally loaded passive piles Ekici, A.; Huvaj Sarıhan, Nejan (2014-06-20) Three full scale field experiments reported by De Beer&Wallays (1972) and Esu&D'Elia (1974) have been modeled using 3D finite element method with PLAXIS 3D. Shear box models were established to eliminate the effect of site geometries and slope angles which were not reported in these cases. Lateral movement of an unstable soil and loading of passive piles were generated by prescribed horizontal surface displacements in the upper half of the shear box model. Measured field values of pile deflection, bending m...
