Abstract

Openings in pressure vessels are usuallu designed based on empiric formulas. The doubts on the results obtained by this method leads to high Project safety factors. The use of the finite element method reasonably increases the reliability of the project. Although the method allows to use lower safety, building models of openings in submarine hulls are not Always simple tasks. And there i salso considerable additional work to be done when a parameter needs to be changed during project or optimization. The finite element method comercial software are usually generic; so they can be used to solve a great number of problems of different areas. Being generic the user usually needs time to learn how to use the program to solve his specific problem, which in a great number of times does not very much. A program was developed to generate finite element models to study openings in submarines hulls. This program has a friendly user interface and permits the generation of reliable quality models with low man time cost. The use of this tool can increase the reliability of the models, making it possible to execute convergence tests, and to test a greater number of different solutions. (AU)
