Summary

MICROCOMPUTERS IN ENGINEERING

The previous chapters of this book have focussed attention on the basic FE theory for elastic and small-deformation elastic-plastic applications. The latter were illustrated by a very simple analysis of the tensile test.

In this chapter, we shall look at problems more closely associated with realistic metalforming processes. The first part of the chapter examines a PC-program written in BASIC that can be used for demonstrations or for student tutoring. A listing of this program is given in Appendix 11.

The second part of the chapter describes a FORTRAN program, implemented on a large-memory micro, that is designed for more serious metalforming studies.

No attention has been given so far to the machines on which FE analyses can be performed. Where mainframe computers or workstations are available, this is not important but in microcomputer applications, how the machine operates and the importance of selecting the right operating system, software and processors cannot be taken for granted. The decision as to what equipment is most appropriate must be made by the individual user, based on carefully assessed requirements.

A general introduction to microcomputers is given by Avison [4.1] in which many aspects of micro hardware and software are discussed, and comment on buying a micro is included.
