This book was released on 1963 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A list of the problems related to buried and submerged cylinders that are solved in the literature is given. This includes both rigid and flexible cylinders and both acoustical fluid and elastic solid surrounding media. The works of Baron and Yoshihara, in particular, are discussed at some length but only graphical data is cited due to the complex nature of the solutions. Using this data, an experimental program for the blast load generator is presented. Also included is a brief discussion of the methods of numerical integration of a function when a response to a step function is given. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The results of the study indicate that there are certain regimes where the elastic theory could be used to determine the dynamic magnification factors. Further, elastic theory does not appear to be applicable over the entire pressure domain nor does it appear to predict the location of the maximum strain. A majority of the observed phenomena may be explained by the fact that the static transmissibility of the soil increases in higher pressure regions and by the fact that the dynamic transmissibility is higher than the static for the low pressure regions. Both the static and dynamic transmissibilities seem to converge in the higher pressure regions. (Author).

This book was released on 1968 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general objective of the investigation was to study experimentally the behavior to failure of flexible, horizontally oriented cylinders buried at various depths in dense, dry sand and subjected to either static or dynamic surface overpressures. Static and dynamic tests were conducted on 33 different cylinders, fabricated of high-yield-strength aluminum. Results indicated that collapse of the cylinders occurred while the strains in the cylinder walls were still in the elastic range. The cylinders buried at the shallow depths (zero to one-half cylinder diameter above the crown) collapsed by a catastrophic snap-through or caving of the crown. For the cylinders buried at depths of three-quarters to two cylinder diameters above the crown, the mode of collapse was an instantaneous elastic buckle that occurred at the spring line or invert of the cylinder. The collapse mode of the cylinders under dynamic overpressure was similar to that of the cylinders collapsing under static overpressure. The results of the investigation verified the applicability of an equation for predicting the static collapse overpressure for smooth-walled, horizontally oriented, buried cylindrical structures and entranceways. The hoop-compression theory was found to be applicable for analyzing the structural design to determine if the cylinder would collapse in the elastic range. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of an experimental investigation of the response of horizontally oriented buried flexible cylinders to dynamic loads. The objective of this study was to investigate the effect of variations in peak over pressure, depth of cover, and cylinder stiffness on cylinder response. All cylinders had a mean radius of 4 inches and a length of 16 inches. Cylinders of two different wall thicknesses were tested at depths of cover ranging from 0 to 8 inches and peak overpressures from 98 to 525 psi. These experiments showed that the surrounding soil does greatly increase the dynamic buckling strength of a thin-walled cylinder. It was also shown that a small change in the depth of cover could have a significant effect on buckling strength. Peak strains sometimes exceeded yield strength values, but they did not cause failure of the cylinder. Peak overpressure and depth of cover not only affected the magnitude of response to applied loads but also affected the location of the point of maximum strain. Peak strains and deflections at the crown and invert were more sensitive to changes in peak overpressure and depth of cover than were the strains and deflections at the springlines. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The general objective of this investigation was to study experimentally the behavior to failure of flexible, horizontally oriented circular tubes buried at various depths in dense, dry sand and subjected to dynamic surface overpressures. Dynamic tests were conducted on ten brass tubes in the Small Blast Load Generator. The tubes had a wall thickness of 0.005 inch, an outside diameter of 4 inches, and a specially isolated 5.75-inch-long test section. The tubes were flexible and had a stiffness EI/R3 of 0.018 psi. To examine the effect of depth of burial, tests were conducted in dense, dry sand at depths ranging from 1 to 16 inches, or four tube diameters above the crown. The dynamic tests were conducted at overpressures ranging from 6.2 to 34.9 psi. Measurements were made of the applied overpressure, and the tube deflection was recorded by means of a high-speed camera linked to the pressure-time base. Results indicate that collapse of the tubes was initiated by a buckle that occurred along a longitudinal seam where the tubes were spliced. The dynamic collapse overpressure increased greatly with increased depth of burial down to a depth of one tube diameter; subsequently, the increase in collapse overpressure with increase of burial depth to four tube diameters was insignificant. The dynamic collapse overpressure was approximately the same as the static collapse overpressure as determined from correlation with previously reported results. The results of this investigation have verified the applicability of an equation for predicting the dynamic collapse overpressure of very flexible tubes. (Author).
