List of Symbol s . 



p = maximum pressure of incident pulse. 



Pj = pressure in incident pulse. 



P^ = pressure in reflected pulse if plate were stationary, 



p = pressure due to motion of plate, 



f = time constant of incident pulse. 



C = velocity of sound in water. 



X = distance from centre of plate along axis, 



y = deflection of plate. 



R = radius of plate. 



r = distance from centre of plate along radius. 



s = distance between two typical points on the plate. 



p - density of plate, 



h = thickness of plate. 



CTjj = yield stress of plate. 



Pg = density of water,

 F = force on plate. 



U = velocity of plate. 



U^ = maximum velocity of plate. 



N means that an equation is non-dimensional.
