Amirkabir University of Technology Amirkabir Journal of Mechanical Engineering 2008-6032 44 2 2013 02 19 Finite element modeling of T-shaped connector panel - sandwich subjected to tensile loading Finite element modeling of T-shaped connector panel - sandwich subjected to tensile loading 11 19 28 10.22060/mej.2013.28 FA Seyed Reza Khalili Aydin Ghaznavi Osgoee Journal Article 2014 03 14 One of the disadvantages of sandwich panels is their joints, which usually decrease the efficiency of sandwich structures. The T-joint is one the most common joint for sandwich panels. This paper deals with the numerical study of the T-joint under static loading. The results of FEM analysis are validated by the experimental results available in the literatures. In general, the failure load predicted by the FEM is in good agreementas compared with the experimental results. In the modeling of the adhesive between joint components, contact elements and cohesive zone material model are used. In addition, damage and core shear failure of the base panel are modeled by using a written macro code in the ANSYS software. Therefore, both failure modes of sandwich panel joint are investigated. In addition, the effect of the joint geometry and material of the core of sandwich panels on failure modes and failure load are studied. Finally, the results show that changing the material of the core of the sandwich panel increases the joint failure load.
