Developing and understanding a model involves several logical steps, one of which is determining which parameters are the most influential on model results. Model elements that exert the most influence on model results can be identified by a sensitivity analysis. System models, such as the one shown in Figure 2, are used to approximate various engineering, physical, environmental, social, and economic phenomenon. In addition the following assumptions were made The nodes at the base of the substrate were constrained in both x and z directions. The following boundary conditions were imposed : The nodes on the axis of symmetry z of the sphere and the coated substrate were constrained in the x direction. The top of the coating is the ‘slave’ surface. According to ABAQUS user manual, the indenter surface is defined as the ‘master’ surface since the indenter is rigid body. The interaction between the indenter and the coated substrate is modeled as contact pair without any friction. The entire model consists of approximately 180,000 elements depending on the coating thickness.įigure() zoom in of the contact region in the coated substrate The Reduced integration option available is used to save calculation time. Inaccuracies within the FEA results can stem from various sources including modeling, input of material properties, mesh density, unrealistic stress concentrations, loading conditions, environment, etc.įinite Element Analysis (FEA) is an important engineering tool used …show more content… The element types used in ABAQUS are ‘CAX8R’, in which the letter or number indicates the type of element which is of continuum type, axi-symmetric in nature has 8-nodes quadratic and reduced integration.

One of the major topics within Finite Element Analysis (FEA) is how to present results and verify whether the results accurately illustrate the loading condition.

Finite element analysis (FEA) software package ABAQUS version 6.14 was used in the indentation simulation which is a commercial product. In the present work, the finite element method was used to study the elastic-plastic indentation in layered materials.
