This report is concerned with the analysis of the behavior of arch structures under dynamic loads. A numerical procedure is described for the computation of the dynamic response of circular arches subjected to transient forces ...

The Ritz energy method is used to obtain solutions for an interior panel of a plate or slab which is continuous over a rectangular grid of flexible beams supported by columns at their intersections. It is assumed that ...

An important class of structural mechanics problems deals with the stress analysis of bodies in contact. The primary objective of this study was to develop a system capable of solving large and complex frictional contact ...

This report is the culmination of an extensive experimental and analytical investigation of the loading response of PCRV head regions conducted by the University of Illinois under the Oak Ridge National Laboratory Program ...
