Abstract
The solutions of many problems in seismology may be obtained by means of ultrasonic pulses propagating in small scale models. Thin sheets, serving as two dimensional models, are particularly advantageous because of their low cost, availability, ease of fabrication into various configurations, lower energy requirements, and appropriate dilatational-to-shear-velocity ratios. Four examples are presented: flexural waves in a sheet, Rayleigh waves in a low velocity layer overlying a semi-infinite high velocity layer, Rayleigh waves in a high velocity layer overlying a semi-infinite low velocity layer, and body and surface waves in a disk.

© 1954 Society of Exploration Geophysicists. Manuscript received by the Editor December 7, 1953. The authors wish to acknowledge the assistance of many co-workers at the Lamont Geological Observatory. In particular, Mr. Charles Kershaw constructed all the electronic gear and designed the new components. Mr. James Dorman and Mr. Donald Schiller carried out the computations, and Mr. Louis Collyer built the mechanical parts of the apparatus. Mr. Paul Pomeroy made many of the velocity determinations. The Carter Oil Company generously gave assistance in the design of circuits used, through Dr. Franklyn Levin, who participated in the seismic model work for that company.Attached Files
