Abstract
A computer program, STAGS, for analysis of the behavior of shells of general shape has been extended by the addition of a capability for transient response analysis. A brief discussion of the numerical integration procedures included as options in STAGS is presented here, together with some numerical results obtained by use of the program. The results are included to demonstrate how rapid development of computers and numerical analysis methods has enhanced our capability to solve complex shell stability problems. In addition, they illustrate some facets of shell behavior under transient and static loading.
The applications are concerned with an axially loaded cylindrical shell with unstiffened rectangular cutouts. The effect of the loading rate on the shell response is studied. The definition of a dynamic buckling criterion is discussed in view of the results obtained. Also considered is the possibility of determining a static collapse load (limit point) by use of a transient response analysis with the load applied slowly.
