Özet

FEMis an ongoing and iterative process where the engineer and the computer work together. Basically there are three stages toFEM, with the engineer making decisions along the way: Pre Processing includes developing the geometry of a model, assigning physical and material properties, describing the loads and boundary conditions, and checking the model.. Solving the model generally runs in the part of the software that called Model Solution. Model Solution can solve problems in linear statics, conduction heat transfer etc. Post processing involves plotting deflections and stress, and comparing the results with failure criteria imposed on the design, such as maximum allowable deflection, material static strengths. FEM can show the analysis results in different display formats - deformed geometry, criteria, contour, and others -. FEM offers a complete set of tools for automatic mesh generation, including mapped mesh generation and free mesh generation. Both mapped meshing and free meshing can acces geometric information in the form of points, curves, and surfaces. In mesh areas, FEM generates shell elements, and in mesh volumes, solid elements. FEMs boundary conditions task provides to create loads, restraints, constraints, and degrees of freedom sets. Each load and boundary condition can be defined directly at nodes or along element edges or faces. With all parts of the model defined - nodes, elements, restraints, and loads - the analysis part of the model is ready to begin. The system can determine approximate values for stress, deflections, temperatures, and pressures. An analysis requires the following information:. Nodal points: Spatial locations in the geometry of the model.. Elements connecting the nodal points. XV

Özet (Çeviri)

. Material and physical properties.. Boundary conditions, which consist of loads and/or restraints.. Analysis options: How the problem will be evaluated. For each element, the system formulates a standard set of simultaneous equations to relate physical quantities. The Post Processing task can display the results of an analysis, which exist in the model as analysis dataset. This task can generate displays of deformed geometry, contour plots, arrow plots, criteration plots, XY and XYZ plots. FEM can show stress/temperature contours as well as full element color shading or stress/thermal gradients on the andeflected and the deflected model.
