A COMPARATIVE STUDY OF LINEAR CONTACT PROBLEMS IN SOFTWARE SIMCENTER FEMAP WITH NASTRAN

Abstract

The aim of this article is comparative analysis of results obtained using the linear contact between the two plates set at an angle of 90° in software Simcenter Femap with Nastran. For consideration of setted problem two models of different dimensions and load values, with different type of elements and FEM mesh density were analyzed. The boundary conditions and the mode of action of the load are the same in all considered FEM models. For comparative analysis in FEM models different combinations of 2D-shell elements of the appropriate thickness and 3D elements (hexahedral) were used for analysis. The changes in stress values and node displacements in the contact regions in dependence on the FEM mesh density and different type of elements in contact regions were considered.
