Post-processing stage involves developing graphical display of results. Functional values such as displacements or temperatures are only evaluated at the nodes of the finite element mesh based on the calculations of the solver during the processing stage. A graphical display of results however needs continuous plotting of variation of a parameter in the form of 2D contours or 3D surface images. This needs appropriate interpolation schemes, and the size and distribution of the finite elements and the complexity of the problem domain will have direct influences on the ability of the package to capture representative profiles. 5.4 Preprocessing in Abaqus The first step in the process of analysing the stress fields on the two components under study is to develop solid models of the two components to be investigated. This is done using the pre-processing Part module of the Abaqus software. There are two methods of creating a part geometry in Abaqus. One is to directly create the model geometry using the sketcher tools of the Part module. However, considering the relatively complex geometries of models under investigation, this may not work. The other method is to directly import solid models created using other software packages. Both flat and curved layer models developed using Solid Works are imported into the Abaqus Part module. For compatibility however, the solid models need to be saved in the IGES format initially. The next step is to create the material properties, for which the Material module of Abaqus is used. It is necessary, first to develop the material property data Fabepoxy, the experimental material for the current analysis is not a very common polymer, and being a propriety material, there is only limited data made available. The following are the details obtained from kraftmark.bz 110
