Summary:

Four applications of Interactive graphics to structural analysis are described: finite element modelling, computation of section properties, analysis of suspension loads, and dynamics of frame crush. The graphic system used consists of a Bendix Datagrid digitizing table, Tektronix 4014 storage type display tube and hard-copy unit.The digitizing table is used to obtain three-dimensional nodal co-ordinates from drawings. These points are used to generate finite elements interactively, and the data thus generated is interfaced with a number of batch mode computer programs. Results are stored on a disk file, and the graphics system is then used to view deflections, mode shapes and stress patterns. Section properties of beam members can also be determined on line by digitizing sections into straight line segments. In the analysis of suspension loads the graphics system is used to check model geometry and to view the results computed by a large displacement program. The simulation of dynamic frame crush illustrates the use of a program that allows interactive composition of output variable plots
