Conversão do programa de BMINES de elementos finitos para utilização em microcomputadores.

Abstract

One of the great difficulties arising from the use of numerical analysis software packages comes from the requirements of hardware required for generating consultant solutions of large problems, and are also related to the manipulation and interpretation of output. Frequently, some software packages are designed for large systems and therefore their utilization becomes restricted to users having access to those type of equipaments and also needing an advanced knowledge of the characteristics of the machine and operating systems. Thus, a user's manual of great detail and easy to use is required. This dissertation presents the conversion for microcomputers of BMINES computer code, for finite elements, developed by US Bureau of Mines, which was designed for mainframe computers. Also, a detailed documentation of the code and a user's manual is provided. The basic idea is to link the powerful resources of that software package for creating a tool useful for the analysis of stress acting in a varied class of structures. In order to improve the interpretation of results, a graphics interface has been added to the code, so that a better understanding of the results is possible. The modified version of BMINES code presented here has been validated by means of some of the sample problems provided with the original code. No significant differences have been observed in the results yielded by both versions of the code.
