Abstract : The scientific approach to a study of soils as an indispensable engineering material is rather new, and its subdivision into soil statics and soil dynamics is of still newer origin. In attempting to answer the question, 'Why soil dynamics' it might be useful to recall the history of testing materials other than soil. The study of steel specimens subjected to slowly increasing static loads was followed by the introduction of vibratory or dynamic loads, which led to the discovery of fatigue effects. A cross-fertilization of both methods took place, contributing to a new concept in instrumentation and recently expanding into the field of solid-state physics. Similarly, the investigation of soil dynamics will feed information back into soil statics and result in a better understanding of both areas from the practicing engineer's point of view, the impetus to study soil dynamics is due mainly to the increased speeds and loads of present-day vehicles affecting subsoils, the practice of dynamic pre-compaction of subsoils, and the discrimination between subsurface explosions (nuclear) and earthquakes.
