【 摘 要 】

Analytical and numerical models of the structures use the geometrical characteristics in most of the problems, such as: calculus of the stresses, of the displacements, in elastic stability problems and others. Being an important problem to be solved, we conceived general methods to compute the geometrical characteristics. Along the time, an interesting question for us was how our calculus methods may be linked to the existing commercial software applications. From this standpoint we started to extensively test the CAD/CAE applications in order to understand their generality and flexibility in the calculus of the geometrical characteristics and, further on, of the stresses. We followed several aspects: if the boundary of a section may be automatically loaded, if there are 'tricks' regarding the definition of the model in the current CAD application, if there are commands/functions for the automatic calculus of the geometrical characteristics and how the results may be exported. We tested AutoCAD, NX, FEMAP/NASTRAN and ANSYS, detailed information regarding the solutions being presented for each CAD. Last but not least, this study is interesting in order to test the results of our computing methods and to assess their accuracy and their level of generality.
