A COMPUTER TO DISPLAY THE DYNAMIC STRESS ANALYSIS OF STRUCTURES

摘要

A finite element simulation program for dynamic stress analysis of underground structures is modified to permit generation of a display data file. The data file may be processed by the display program to generate pictoral displays on an SC 4020 film recording system. The displays graphically represent the physical environment of the structure and provide a means of visually analyzing its static or dynamic behavior. Dynamic changes in displacement and stress are represented as equivalent motion in a series of sequential displays. The display method is applicable to any structural analysis program which determines sequential values of stress and displacement. Program documentation is included in this report. (Author)
