Application to plate components of a kinematic global‐local approach for non‐matching finite element meshes

摘要: Purpose – The purpose of this paper is to investigate and assess the capabilities most common finite element (FE)‐based tools deal with global‐local analysis. Two kinds coupling were investigated: shell solid.Design/methodology/approach issue connecting non‐matching FE global local models, characterized by different mesh refinements and/or types, was addressed introducing appropriate kinematic constraints on nodes at interfaces. techniques available in three FE‐based codes (ABAQUS®, NASTRAN® ANSYS®), assessed applying them a numerical test case (non‐linear buckling analysis square plate). Results simulations compared results obtained for relevant reference solutions.Findings continuity displacements stresses across interface between models influence presence model solutio...
