Abstract:

Finite element structural analysis is gaining wide acceptance in the field of projectile design. In the past, computer memory and storage requirements have limited the application of finite element analysis to large main frame computers and workstations. Recently, great improvements have been made in the computing power of desk top personal computers. As a result, interest has developed in applying finite element software to the P.C. environment. The mathematics and computer algorithms for finite element analysis are readily obtained from engineering references. However, the most tedious and time consuming operation is the generation of the finite element model. A suitable mesh generator is, therefore, required to fully implement any finite element package on a personal computer. This report presents a straight-forward and easy to implement two-dimensional mesh generator for both plane strain and axisymmetric analysis. Computer code listing and examples are provided.
