Description
Summary:Bibliography: leaves 94-96. === This primarily experimental investigation describes a series of experiments on fully-clamped circular plates, rectangular beams and stiffened circular plates. These test specimens were subjected to a uniformly distributed impulse. The impulse was provided by plastic explosive. This was arranged in such a way that a uniformly distributed impulse was imparted to the test specimens. The impulse was measured by means of a ballistic pendulum to which the test specimens were attached. The final mid-point deflections of the plates and beams were measured. The plate and beam results were compared to previous experimental work. A non-dimensional number for plates was modified to include an experimental mass scaling factor due to the ballistic pendulum mass. A non-dimensional number for rectangular beams was developed, including a similar experimental mass scaling factor. Comparing the beam and plate results from this study with those of previous work, using the respective non-dimensional numbers, showed good correlation. The results for the stiffened plates are compared with the plate results.
