SEISMIC MODEL IMPACTER,

Abstract

A new type of strobo-photoelastic impact source is described in detail, including specifications, design, and operation. This equipment extends the model size available, for photoelastic studies of propagating waves, from models having linear dimensions of an inch or two to models more than a foot square. The seismic model impacter unit supplies a 1/8 inch deflection, within a time of 1 millisec, to the model material. This impact is repeated precisely 30 times per second. (Author)
