This paper concerns with the aspects of the Object Oriented Programming used to develop a Finite Element technique for limit analysis of axisymmetrical pressure vessels. The concepts of inheritance, polimorphism, encapsulation and modularity are extensively explored. A friendly user interface based on the MFC library classes was developed to run the analysis processor integrated with two graphical modules defined as modeler (pre-processing) and post-processor. The problem used to illustrated the limit analysis technique implemented is a standard ASME torispherical vessel subjected to internal pressure. The obtained results are compared tiwh other numerical and analytical solutions.
