Modeling and Buckling Analysis of Rectangular Plates in ANSYS

摘要

With plate-buckling problem still being an active area of research in the field of mechanics of materials,researchers need to validate the proposed solutions and theories, using analysis tools such like ANSYS, which isa robust general-purpose finite element analysis tool. This article investigates modeling and buckling analysis ofrectangular plates in ANSYS? Mechanical APDL, Release 17.1, through a series of comparative studies conductedon various models and options. Shell and solid models of homogeneous and functionally graded plate (FGP) usingvarious elements are investigated. Expressing boundary conditions on both shell and solid models of plate forbuckling analysis is discussed. Procedures of buckling analysis in ANSYS are presented and effects of meshing,boundary conditions and element options are examined though comparative studies. Results obtained from ANSYSare compared to various analytical solutions.
